I hate it when parents do that. Mine are usually pretty lax about rules, but once in a while they'll crack down hard on something like getting home at 6:45 rather than 6:30 - because apparently I have a curfew that they never mentioned and never care about except for right now.

*hugs* That's always such a bitch. I'd say "can you try talking to them?" but... yeah. Good luck dealing with it? *sigh* *hugs!*
