The girls were sitting at the table having a snack. I hear Abby giggle and look over. Don’t see anything odd. I hear Abby giggle again and look over… again, nothing odd, but this time I notice Emi is leaned over quite a bit.
Abby giggles again and I *know* something is goin’ on. So, I peek a bit closer and see Emily is tickling Abby’s knee. She’s very lighly tickling her… and Abby’s response is a giggle. Emi then proceeded to seriously tickle her sister, who in turn laughed quite forcefully.
So, now we know Abby is ticklish AND Emi knows what to do to make her laugh!
