Our au pair, who is leaving in seven weeks, has started to do some things that are really getting my DH and I scratching our heads, and I was wondering if this is a 'pre-departure phenomenon' to some extent, and one that has been experienced by other MNetters.

This is out of usual character, but the frequency of these moments is increasing, and I'm starting to think there is a quiet rebellion of sorts going on. Has anyone any thoughts?
