what does "tell me anout it" actually mean?
Ive seen in movies that "tell me about it" means im agree with you what you just said was right.
but the thing is when i actually use this line and it causes some misunderstanding.
For example:
A:i really think she is overreactting.
B:tell me about it.
A:Well,she...(explain the story...)
So,what does tell me about it really mean??
Thank you!
