why do humans always need to be the one with the bigger story?
it's the classic case of "...my fish was THIS big!" whenever someone is telling a story, there is always someone else who needs to have one up over them. when you got two free tickets to a concert, your friend got three. when your son got a 97 on his gemara test, your neighbors son got a 99. when you got a two week paid vacation bonus, your co-worker got three weeks.
and what about when someone is experiencing a tragedy "my wife is sitting shiva for her mother" "oh that's really sad...i remember when my mother-in-law passed away..." people are so eager to talk about themselves. "oh you're having a bad day? don't worry it will get better, i remember last week when i felt like nothing was going right..."
people don't do it personally. it's human nature. you've got to be aware of this in order to catch yourself. but I've noticed that people who are willing to listen more and talk (especially about themselves) less, are people that you want to hang around with, because you feel like you're actually talking to a person whose willing to listen. you're having a conversation, a dialogue. not two monologues.
