I Am Prone to Inappropriate Laughter

I have a dark sense of humour and find it easy to laugh at the strangest of things.It can be embarrassing, but those that know me well forgive me as they know I can't help it.I do realise that it's something that I can't change , but one thing I would never do is make fun of anyone,or be cruel,my inappropriate laughter has never hurt a soul,and never will .
