I know I should be choosing numbers from that list and whatnot, but being different really feels nice...
I simply believe feelings shouldn't be openly expressed (openly = publicly), not positive nor negative, they (feelings) are many times a weakness. I do believe that any open (again, by open I mean public) expression of feelings will prompt people to jump at the opportunity and try to exploit said weakness.
Expressing feelings to close people (good friends, loved ones, etc.) is OK, you might someday regret it because they were not as worthy of trust as you thought but hopefully you'll at least learn something about human nature from such experience.
Mind you, I'm not saying it's wrong/bad/negative to have feelings, I surely have them, everyone does, they are a part (good or bad) of us, humans. But they are YOUR feelings, you are the one who needs to "take care of them", no one else will, nor should you expect them to as they also have their own feelings to take care of. (this last commentary mostly applies to people who think offloading their feelings to someone else will solve everything)
So, I guess my idea goes along the lines of: People suck, you wouldn't share something as personal as feelings with them, right?
