People who interrupt you

I am just so angry right now, I want to scream! This is totally unlike me but lately this has been getting to me. I am almost sure that I mentioned this in an earlier post but it just seems to be getting worse and maybe I am the one over-reacting here, I don't know. I know that I can't expect Andy to be PERFECT, but I really wish that he'd stop interrupting me when I am talking. To me there is no way of showing more disrespect than by interrupting someone while that person is talking. Maybe it was just the way I was raised. I remember how my parents used to discipline us if we interrupted them and maybe it just stuck. It is just that the way I see it, someone can't REALLY be listening to you if they have been thinking of saying whatever they interrupt you with. It just doesn't make sense and it makes me angry because I don't want people to PRETEND to be listening when in fact they are not. Just say you don't want to listen then.
