Is it a nervous laugh? Or true laugh at funny things?
I laugh a lot but it’s because I find many things funny. Yes I’ve been known to step out because I couldn’t stop laughing at something. My whole family is this way, it’s not a nervous laugh or mental confusion. We just like to laugh.
If you were laughing at something dumb you saw on tv, I could relate to that.
Having said that, if you think it’s excessive and it bothers you maybe you could ask your t what they think it might be?
