Letting Go . . . Temporarily

It is the chance of a lifetime. Our daughter is studying French as part of her high school curriculum. We have native French speaking friends that live in (gulp) Vancouver, BC. They would LOVE to have her for a couple of weeks. They used to teach her horseback riding from when she was about 6 to about 13 when they moved away.  They've promised to speak ONLY French to her, and to let her muck out as many stalls as she wants.

There's still enough summer and still enough money in the "flee before the mountainside falls on your head" fund for her to go out there for 10 days or so . . .without me. If I'm there, people will speak English.

Sigh.

What do you think I should do?
