I've gotten used to drinking plain, lukewarm water. At work, I'd fill my water bottle with ice water a few times a day. The fridge had an icemaker that dumped ice into a bucket in the freezer.
Only a week at home, and there was no way I was going to refill my ice trays that often. So, my water starts off cold, but by the time I finish it, it's not. Even when/if I go back to the office, I don't think I'm gonna be sticking my hand into the communal ice bucket...
