person A: Public speeches always get me. It makes me very nervous and I just can't do them.
person B: I feel the same way. I have social anxiety so standing in front of a crowd is pretty terrifying. 
person A: I will start speaking gibberish and sweat bad. Not only that but my face turns so red!!!
person B: Oh man! Just stay confident! You have to keep the negative thoughts in the back of your mind.
