I DoIf something is funny I laugh out loud, something I guess I got from my family, when we are enjoying ourselves you can hear us from the street. I never knew this was strange until I noticed that in some restaurants people would turn and look as we laughed at some joke one of us had made.
Even today someone was telling me something funny, I laughed, they smiled. I am quiet, yet I am loud when I laugh and I am having fun. I find it interesting that many people are loud only when they are angry, yet quiet when they are laughing. Is that not strange?
So yes I LOL, all the time, and don't care who hears me when I am having fun.
