Making stupid mistakes..

I can't quite figure out if some people know that line between stupidity and down right idiocy. Some people never learn. You can tell them a million times that they are being stupid or making mistake after mistake, but it doesn't matter because they inevitably have to learn it themselves. They move to fast in a relationship and they wonder why 5 months down the line it didn't work out. They decide to make a stupid life decision and wonder why it blows up in their face. People need to learn from their mistakes. No one is perfect. but repeating the same behaviors over and over... Not so smart.
