E was tired and crabby when we got home last night. She did the chores she need to - unpacked her backpack, fed the cats - and then collapsed on the couch. A few minutes later, I heard her say, "Stop it, L!" then a few seconds later, she shrieked angrily, "STOP IT, L!"
I called L into the kitchen and said, "I heard E ask you nicely to stop doing whatever you were doing. Why did you keep going so she got angry and frustrated?"
L protested, all wide-eyed innocence, "But I was doing something different each time!"
She won't know until she's an adult how hard of a time I had keeping a straight face. Apparently, the first "Stop it!" was for smacking a butt, the second was for tickling.
