Nervous Reaction

It has come to my attention (i.e. I have recently been ridiculed by Hubby) that I laugh after each sentence when I am talking to certain people. I never really noticed it before, but now that he's pointed it out, I totally notice it and it drives me crazy! I really can't even help it. As far as I can tell, I do it when I am asking someone to do something (i.e. to the nanny: "Can you bring in the girls' stuffed animals from outside?") or when I am talking about an uncomfortable subject (i.e. "Well, where do you think the miscommunication between us was?") or if I am talking to someone that makes me nervous (i.e. "I would be delighted to come in for an interview!"). In any event, my radar is up and I'm gonna try to curb it. have I been unknowingly annoying people all these years?

hee hee?
