Bahaha I've never done that, I get too scared.

Oh me and my friend did. We were messing around before looked at each other and just laughed. We felt mean but just couldn't help it
The funniest was when i laughed when a teacher was telling me off so got a detention

Yeah! The worst thing is when you're meant to do like 2 minute silences...and it's so awkward that all you can think of doing is laughing...

Yus and when you can't laught because somethings serious but because you can't laugh you then need to. So you start laughing :')

Haha! I know! Bless Or when something funny happens and everyone laughs, but you're the last one to actually stop. And every time you try to, you just can't.

Aha same. I think it's the worst though when you think of something funny and just burst out laughing.
Did that once in my Geography class :') They never understood because i was the only new person but i remembered the lesson in my old school where the teacher had a hissy fit when he was teachering that lesson. Made me laugh. Pretty sure they now all think i'm a nutter :P

I do that a lot when I'm having a funny conversation. I look round and everyone it looking at my like

My sister thinks i'm strange as i'm sitting here giggling to myself about it now :P

Baha, fair enough then.

I bet but my sister was outside so she wouldn't have been best pleased
