Beat around the bush

Meaning: avoid the main topic, not speak directly about the issue
Grammar form: verb; to beat around the bush
Verb Forms: beat-beat-beating-beaten

Example 1:  She beat around the bush for a while before telling her friends everything about the new guy she was dating.

Example 2:
Son:  Mom, I borrowed your car last night to go meet some friends.  While I was driving, I got a text and started to read it because I thought it might be urgent.  Unfortunately, I was focused on my phone and didn't really pay attention to the road.  Because I was multitasking while driving, something bad happened.  I am sorry, I know it's my fault.
Mon:  Oh, stop beating around the bush and tell me exactly what happened.
Son:  I crashed your car into a tree!

Explanation
The expression to beat around the bush is used when you are feeling nervous or scared to tell someone something right away or directly because you are worried or unsure about how they will react.

In Example 1, the girl is nervous about telling her friends about the new guy in her life.  She clearly cares about what they think and she knows that her friends would be very curious about this new piece of information.  She is just teasing her friends by not telling them instantly in order to build excitement and suspense.

On the other hand, in Example 2, the son is definitely not in as positive situation as the girl in example 1.  Here, the boy has made a big mistake and is hesitating telling his mom about what he did.  He knows that once his mom finds out about that happened, she won't be happy.  That's why he is stalling giving direct information as much as possible, not out of excitement, but out of fear.

Break a Leg

Situation #1
Martha:  I’ve been practicing all week.  I have a concert tonight.
Sam: I hope you break a leg.
Martha: Thanks!

Situation #2
Sarah: I’m excited to go to the theater tonight and see your performance.  I love Romeo and Juliet.
Terry:  It’s a very dramatic story.  I have been in this play before, but it is the first time for me to play Mercutio. 
Sarah: I can’t wait to see how you do it.
Terry:  Thanks.  He’s a difficult character.
Sarah: Break a leg.
Terry:  Thanks so much. I appreciate that.

Meaning:  “Break a leg” doesn’t seem like a good thing to say to anyone but it actually means “Good Luck” or “Do a great job!”  This idiom is commonly used in the world of stage performance and it is said to a person before a performance.  It seems that the speaker is wishing the performer to have an accident on stage, but in fact, it is the opposite.  The speaker is telling the performer to have an outstanding performance.

This is a very old idiom whose exact origins are not known. In the tradition of theater as well as in horse racing, there was a superstition that if you wish out loud for something good to happen, then the opposite will happen instead.  So it’s best to wish someone a bad thing, like break a leg, so that the person will have the opposite – a good thing.  People say: “I hope you break a leg” so that good luck will come to the person.

One theory is that when a performance is so great, then the performer has to take many bows when the show ends.  In a bow like a curtsy, one must put a leg behind the other and bend it while bowing. So it looks similar to a broken leg next to the straight one.

Example #1:

Example #2:
Tom never came home to his girlfriend last night. I wish I could have been a fly on the wall when he told her the reason.

Example #3: The rival company is going bankrupt. If I could be a fly on the wall at their meeting I could learn what is going on there.

Example #4: They made the documentary with a fly on the wall style.

To be a fly on the wall: This idiom uses the image of the small but silent fly resting on the side of a wall, and observing while human activity continues in the room. The definition is to listen and watch others closely but they don’t notice your presence. To observe a situation as if you are invisible.
 
In example #1, the speaker wants to hear how the co-worker is going to explain his failure and how the boss will respond to him.
 
In example #2, the speaker is interested to hear the boyfriend’s excuse and his girlfriend’s response and would have liked to hear how they interacted with each other.

In example #3, the speaker is from a rival company and wants to learn what kinds of internal difficulties the company is facing without them knowing that he is listening.

In example #4, a fly on the wall documentary is an observational style of documentary filmmaking in which the camera records participants doing things in their normal way and responding to situations in their normal way. The style avoids using interviews. The effect is such that the camera, and therefore the viewers, too, are like flies on the wall observing the situation.
