When my daughter was in preschool, her spring break week was the same as that of the university and we used to go on family trips for part of the week. Once she started elementary school, her spring break and her parents' spring break went out of phase and we shifted our family trips to the winter break (in addition to summer trips).
That means during my spring break I stay on campus and have a week filled with (relatively) uninterrupted days to get caught up, to work on papers and proposals, and to recharge for the rest of the academic year. I love that week.
BUT, here is a typical conversation I have numerous times every year at a certain time:
Other person: Does your spring break coincide with your daughter's?
FSP: No, they are always different weeks.
Other person: Oh, that's too bad.
FSP when feeling reckless: No, it's not. It's great. I love having a week to read and think and write and be in the lab.
FSP when not wanting to deal with the usual frowny face, taken-aback, you-are-a-scary-scary-person (and possibly a Bad Mother) response: Yeah, it is.
What is really too bad is that I don't always feel comfortable admitting how much I like working in my office over spring break, but if the person to whom I am speaking doesn't know me well, I might not have the time or inclination to explain the overall context of my life so that they can understand why I am not necessarily a scary scary monomaniacal child-neglecting research person, e.g. (1) We go on lots of family trips, just not that particular week; (2) My daughter is a very happy and interesting person who is glad that her mom loves her work; and (3) I love my work.
Of course, when my daughter's spring break rolls around, we have a bit of a challenge. Depending on our teaching schedules, conference schedules, and so on, some or all of us go on a trip for part of that week, or one of the Insane Grandmas helps out, and somehow we manage (and typically manage to enjoy that week as well).
