The other day at work one of my coworkers ate my lunch I left in the break room fridge.
i bet you were frustrated with them. Did you confront them?
No, I was just upset and confused about why someone would do that. 
I agree. Im sorry for that. I hope they didnt get you too sad. Maybe they thought it wsa theirs for some reason
I guess they needed that lunch more than I did in some way, I just hope they respect my stuff in the future.
I agree. Go talk to them and express your frusteration and anger with them. Maybe he will get it.
