One of Mabel's favorite things to do at Nana's house was to play in Molly's water dish. Whenever there was quiet, there was Mabel splish-splashing with a triumphant smile on her face. Molly very much dislikes her area being disturbed, by the way. In case you were curious.
When I caught Mabel in the act, I scolded her, wiped her up, and sent her on her way. Cause that's my job as her mom. I repeated this 211 times.
When Nana caught her, the punishment was entirely different. Much more brutal. Nana scolded with a smile on her face. Then instead of wiping her up, she stripped her down and sat her at the sink.
