It was until my therapist pointed this part out that made me more aware of my nervous laughter tendencies; yes, I laugh at inappropriate times.

And it affected me throughout life... I didn't really know or have any explanation (or rather excuse), except to say that I usually use this to cope.

It was until I realize it is a thing... and it isn't easy to share/let people around me understand as they find it hard to accept my socially inappropiate behaviour.
