At my former job, they were big on training people to be manage people. And one of the sessions we had was lead by the Dale Carnegie institute. THey gave a bunch of advice. Some good, some controversial (including the bad news sandwich).
Anyways, one of the pieces of advice I liked was "The sweetwest sound is the sound of your own name", meaning, say people's names at work. When you pass them in the hall, say "Hi Bill" instead of "Hi".
Now obviously you can go overboard (I'd recommend not saying a person's name more than once per conversation), but I think this is a really easy thing you can do at work.
Quote of the Day:
From a newspaper headline, about MLB players using pink bats to celebrate mother's day and the fight against breast cancer:
"A mother's day gift that's sure to tickle her pink"
