What's in a name?

Today the girls were playing together and pretending that Lila was Evie's puppy dog. Evie took her for a "walk" around the house on the end of one of my measuring tapes.  It was so cute, until Lila made wrong turn and Evie called out to her to heel. "Pissty! Stop it! Come here Pissty! Come here!"

"What did you just call your sister?"

"She's not my sister, she's my puppy and I named her Pissty. Isn't it so cute?"

Uh- what do you say to that one?

Add another reason to why we won't be getting pets anytime soon. And we won't let Evie name them if we ever do get one...
