Sounds like a Princess has been knocked off her pedestal infront of her commoner and she's a bit embarrassed about it!
Don't be pissed, just enjoy it and be oh so grateful that your babies are as wonderful as they are!! And be SURE to tell the groomer that SHE referred you!!! So they can THANK HER when her apt rolls around in a few weeks! Hopefully they will tell her what a joy your dogs were!
Won't that just eat at her! No need to give her any of your energy!! The best revenge is living well! Stick it to her by enjoying yourself! Sounds like you have a great groomer who hopefully will keep you at the front of his books!
