You've done your part by trying to contact this Mom..not once, twise but five times!

I'm assuming that one more month means that your dealings with this family will be over soon. Then you will only see them when you both happen to be outside at the same time. You can then wave, smile and think to yourself not my problem any more.

Ya, I learned not to take any neighbours and caulk this one up to a lesson learned like I did.
I don't think she will find too many people out there that would put up with what you are ~ they will be kicking themselves that they let a great provider go!
