I have found that the people who do this, are selfish and feel that everything needs to be centered on them!  They seem to have a very low personal self esteem!  When someone does this to me, I say "Excuse me, but I was not finished and it is considered extremely rude to interupt someone unless it is a dire emergency.  When I am finish YOU can have your say."\nThat usually shuts them up and sometimes they excuse themselves from the conversation!

You've been listening to too much George Carlin.\n\nActually the reason is that they do it out of force of habit. They are normal medical people, and they are just administering an injection. They do everything normally out of habit. They are trained this way so that they can perform under high-stress situations.

People make mistakes and they cannot forgive themselves. They try to blameselfs more to please other people. They end up hating themselves. They think everything is their own fault.

It's in their narcissistic nature. But society has changed, so they try to cope with minority groups as best they can: by putting up a good image of themselves in front of people when its in their best interest.

Some people just talk to themselves. I do it because Im the only one who cares what I say....LOL!!! You have to retrain yourself not to do it anymore.

yeah..its irritating.\nsome people do that intentionally.

because its a nature in us as people to invite other people into a misery they them selves are in. Sometimes its funny and interesting to be a coward and talk about somebody else behind there back. I feel if you do something to someone that you yourself would hate if it was happening to you, your a fool!!!

It means that they may have to question their own beliefs and why would they want to do that?  I mean, think for themselves?

Because the only way they know to feel better about themselves is to point out the weaknesses and faults of anyone and everyone else.\n\nAnd it seems that a lot of people think everyone else's life is their business to poke their noses into.\n\nAnd because those people fail to see the good in anything or anyone.

Why would I do that??
65740
Because they want to see how many people they can annoy with it.  They feel because THEY like it the rest of us will.  Not only that they KNOW they are irritating people and like doing that.  It's an immature way to 'jab' people.

Some people do it just because they know they can.  It gives them a feeling of satisfaction.  They cannot feel good about themselves unless they bring someone else down.
656995
Because they're too depressed themselves and have nothing else better to do. They have low self-esteem.

They do it for attention and to take attention away from other women (usually to upset them and feel better about themselves).
