It was a joke!

I didn't understand what you meant with "either don't get to react to in the wrong way". But I"ll answer it according to my knowledge. If someone tells me a joke that I already know then there won't be a laughing reaction from me and if he is telling the joke the wrong way, I"ll just give a little smile and tell him the right joke.

sometimes my friends told me a joke and they laughed first.but i still didn't got it,so i would ask 'what's so funny?'.then there is a chance that they would laugh even louder.but when i don't understand a joke,i will not laugh,i will keep asking them until i understand that joke.lol,i am just too slow.

this has happened to me a few times, i usually try to jus laugh it off and make them feel ok, so that they wont know they bit it on the joke

well ok when someone tells me a joke that either isnt funny or i dont get i tell them. This is mainly because if I dont they'll go tell someone else and be embarased.
