I've always wondered why people are rude to other people from the get go.

If I meet someone, I am polite. I offer a handshake, smile, etc. Not because I have to, but because I am interested in people and I genuinely want to know who they are and what they do.

I don't understand the mindset of 'I've never met you, but I'm going to be rude to you." If more people were genuinely polite and interested in others, half the world's problems would be solved.
