I voted "Summer? I have tank(s) to care for!" because it does seem as if I'm married to my tanks.
Before I had kids there was a definite change in the approach to the tanks. Now that I have kids and too many to-do's anyhow, there isn't the hugest of changes. My tanks are what I get to play with when work's done and everyone else has gone to bed. There's this thin sliver of "me time" somewhere around 1am and I'm hanging onto it for dear life.
Everyone at work thinks I'm tired because I have a baby at home... I'm running with it for as long as I can!!!!! So I can at least honestly claim a level of consistent care to my tanks now. It's just consistently inadequate year-round!!!
Summers are just harder on the tanks overall though. For the most part it seems the heat is a battle, and of course the vacations take their toll too. I can count on something going wrong (sometimes big, sometimes small, but something) .. everytime I go away, ie., when I come back I can expect to find "oh, how quaint, a new problem I have to solve."
