Yipes! Allowing your parents to plan anything unsupervised is always risky, even without the added fun of sudden medical emergencies in places that don't speak English. Hopefully your sister won't end up stranded in Europe :) And at least you got to see Paris, which is my favorite city ever.

BTW, if you really want to find out what's going on with your dad in Paris, you should get in contact with Sara Munro, since she (a) lives there, (b) speaks french, and (c) is not your mom. Her phone number there is (33) 6-71-43-41-56. Here's hoping all the craziness resolves itself shortly.
