Cyndar,
that reminds me of the first time I ever went in for a (regular, not Brazilian) bikini wax. I was younger and way more modest then, but figured the wax lady saw this every day. Then, some other lady just barges right in, and says breezily “oh, it’s just me”. Rather annoyed at the intrusion, I reply (not without a little attitude), “Uh, yes, and WHO are you?”
