person A: I'm nervous about this test I did.
person B: Don't be nervous. I am sure you did alright. It is normal to think that but most of the time it is all in the head.
person A: I studied pretty hard so I'm hoping for a great mark.
person B: Oh good_comma_ then there is nothing you should be worried about then. :) Go relax and distract your mind on something else. All will work out my friend.
