How rude can one person be? Your baby is cute as can be and I like leaving the hair on their legs when they get a short cut too! I don't see why she wouldn't like it, but even if she didn't why say it like that, or at all for that matter? Surely that couldn't give her any pleasure to be rude to you? What would be her reasoning. Probably none! Maybe she is going through emotional, psychological, hormonal, aging, medicinal, or just plain personality problems????? I do try to ask myself if people might be having some of those issues when their behavior is so bizarre like this lady. But I usually don't think that way until I cool off.
Glad you did not have to have a smack-down right there in Petsmart. You are right -- ALL YORKIES ARE PRECIOUS!
