Obviously she had no idea what to expect when she came to your house. I'm sure your friend has told her all the wonderful things you have done with her child and she came expecting to see a mini daycare centre like her child attends now - ie same just smaller. Shocked is probably why she only stayed 10 minutes. Just the fact it was a temporary stopping grounds till he got into a "real" centre would have ticked me off and if it hadn't been a friend I would likely have sent them on their way after 10 mintues myself if she didn't offer to leave.

Just remember anything she said, did or didn't say or do is in no way a reflection of you or your program. I probably wouldnt' contact her again but I for sure would speak with the family that referred her to let her know that you had the interview and that the family just didn't seem to be able to make the transition from a daycare centre to the benefits of a home daycare but thank her again for the referral - make sure she doesn't feel upset. If it was me I would be embarassed to face my caregiver if my friend acted so rude.
