I know Daisy wasn't directing this at bosses here, and don't get me wrong; I've had my share of bad bosses. I'm lucky right now to have some very good ones, too. And I think Drew's a pretty good boss, too, from what I've seen.
Oh, definately not every boss. I like mine right now, so I was happy to tell them HBD!
I can see though that if you aren't particularly fond of the person who is dictating your life for at least 8 hours a day, at least 5 days a week, having to say you appreciate them is...problematic.
