I've googled it and still don't know the answer to this question. I thought the kind ladies here would have a nugget of wisdom about what to do... and it is WAAAAY off topic of cycling.

We have tickets to the Nutcracker Ballet every year. Daughter, 11 yo, wanted to invite a friend this year. I sent an email to the mother last week inviting the friend, and she hasn't responded. I sent another email asking if she got the first email. No response. We're getting close (ballet is 9 days away) and if the friend can't come, we're running out of time to invite someone else. Not sure what to do at this point and wanted to get a broader view of what the proper thing to do would be. I can't really "un-invite" her, and I suppose at the end of the day, we just eat the expense of the ticket and the kiddo doesn't get a friend to tag along if I don't get a response? Thoughts?
