On a side point. I too remember working with someone who I felt didn't like me at all and would barely say hello.One day I mentioned a soccer match our national team played the night before. He talked heatedly about the match and ever since was friendly.I don't much like soccer but this simple interaction changed everything.
Pity it works better with strangers!
