I have the same issue!
In one family, the dad hates stars yet he's the one who constantly wakes up at night to star gaze.

In another family, the eldest son hates workouts but he loves working out as well as quick workouts. The youngest son hates grass but he enjoys playing on the lawn.

Last family, daughter hates brushing her hair but it seems to be her favorite hobby. The mother hates music but she listens to it all the time!

All in all, its pretty odd. But I find it entertaining though. =x
