To Shape Up

EXAMPLE  1:

Dear Zora,

This is the last time I will remind you to wash the dishes after cooking.

We are roommates and we share a space. You never clean up after yourself! I always have to ask you to keep the apartment clean... Sometimes I feel like I am your mother! Seriously, if you don't shape up, I will ask you to leave. 

Sincerely,

Tasha Orushko

EXAMPLE 2:

Dear Tasha,

I don't care what you say! I pay my rent on time and I always wash the dishes!

I am not your maid. I will clean up my mess, but don't expect me to pick up after you.  Am I clear?

You are the one who has to shape up, my friend!

Have a great day!

Zora
