Yesterday I took the twins to Costco to pick up a few things and we made a stop in the bathroom. As the public restroom routine goes (with 6 kids we have routines for everything) each girl goes in their own stall and I wait by the sinks. While I was waiting a grandma lady came in just in time to witness Callie fling open her door, jump into a performance stance and announce, “I TINKLED!”. The grandma started chuckling then Cassie flung open her door announcing the same feat, then she really started laughing (as did the lady in Stall #2). It looked rehearsed although I doubt it could be reproduced.
