Inconsiderate Interrupters

Another huge pet peeve of mine would be when people interrupt me. Whether it's the person I'm talking to or someone coming into the conversation. I find it incredibly rude and incredibly annoying. I'll simply be talking to a friend, when someone else jumps in and starts to talk over me as if I'm not even there. They don't pardon or excuse themselves, they just start talking while it is obvious that I am. The worst is when you're talking to someone and they don't look at you while you're talking, then you realize they're not listening. Then when you tap them or ask them what you just said, they just be like "oh, sorry i wasn't listening." Thanks a lot. The one's I want to slap the most are the ones that interrupt someone else's conversation. The one's that just butt in and think what they have to say is so much more important than what everyone has to say. It's not like I'm talking too slow or too quietly, you people just can't be polite. You can't even manage to say "excuse me" or "sorry do you mind if I ask so and so a question?" Here is a bit of advice for all of you interrupters out there; think before you speak! We listen to what you have to say, even if it puts us to sleep, it's the polite thing to do!
