marginalizing

I was thinking before about how easy it is for people to marginalize other people. I think that most people marginalize & don't realize how much it can hurt others. I think that's why people get so upset when they feel like they aren't given credit that is due to them or maybe why we have acceptance speeches when people receive awards. What is the real purpose of an acceptance speech anyway? Most of the time the recipient of the awards just says some thank yous, but in reality they probably don't normally say them in day to day life. I wish society was a lot more polite sometimes. I think a lot of people would be happier if they felt more recognized & appreciated even if it was just by those that are close to them.
