1) Someone says something / I see something / Someone does something funny.
2) It triggers in my brain as being humorous.
3) My lips upturn to a smile.
4) My mouth opens.
5) My stomach contracts.
6) I let out a sound - one that sounds like this: "Ha! Ha! Ha!"
7) Depending on HOW funny the thing was, I carry on laughing in this manner, or I stop.
8) If I have been laughing for a long time, my stomach hurts.
I don't really make any...sounds when I laugh.. I just open my mouth and push all the air out, and all you hear is me trying to inhale sharply, because I'm going to probably pass out from the stitches in my side or the lack oxygen...
