Good old teenagers
The good thing is I suppose, is that your daughter will see that you are prepared to go through with what you bribed her with - you were true to your word
She will thank you for it (even if she doesn't say so!) and, though it may well not turn out to be true love forvever between them, you gave her what she needed and let it run its course.
So well done to you Meadow, I'm sure he'll have a lovely time with you
Just be prepared for tears when he has to return to the UK.
