Which is an example of body language?

Answer 1

Here is an example that happened to me:

I had someone say to me "hey, how are you doing?" and I really wasn't having a good day so, I started to tell them "well, not so well actually..."

but then I noticed that the person who asked me the question was darting there eyes around as if the wanted to be somewhere else. I knew at that moment that the didn't REALLY want to know the answer to that question, they were just trying to be polite and make conversation. The seccond i stopped talking the person walked away.

Thats an example... you can usually tell what someone is thinking just by watching ther reaction to something you said
