Trapped by grapes

On the way to her last ballet class at Y today, Julia is walking along the curb.
I am pushing Jacqueline in the stroller so we pass a car on the street & get ahead of her.
This is unusual as Julia really likes to be the line leader.
I turn to look behind as I realize that Julia is not with us.
She is stopped & looks up & says "I'm trapped by grapes" ...
There is a pile of grapes on the ground, including part of the curb where she is standing.
She looks quite serious so I encourage her to find an alternative like a quick jump over the grapes.
Julia does & we continue on our way to the Y.
Hilarious!
