Idiom: No problem.
Megumi: I’m sorry I can’t give you a ride home from the airport.
Shi-Young: No problem. April said she would pick me up.
Meaning: “No problem” means, “That’s okay; don’t worry about it.” It’s common to say, “No problem,” after someone apologizes.
Here is another example:
Shi-Young: Thanks so much for picking me up from the airport.
April: No problem. It was on my way.
Meaning: In this case, April means that giving Shi-Young a ride wasn’t a big deal. You can use “No problem,” instead of, “You’re welcome,” but it’s a little less formal.
