I liked this a lot. It had the feel of Rugrats or Our Gang (dang I'm old!). I laughed throughout and thought overall, you did a good job with this. The adults watching them and having no idea what they are doing is funny to me. I only had a few issues with it, but read it all the way first without taking any notes (which is rare for me). Here are my notes:
Rory freezes instantly, finger mid pick. That was funny!
I would have the Mafia Kids with candy cigars.
You had Jeff at “the ice cream stall” and then had A.J. Notice “an ice cream stall.” It almost sounds like another one. Just make them both “the”
I like how all the kids go through the reasons the adults give them for not eating ice cream.
Rambo Einstein, 7, going on 45. Very funny!
Jeff after being hit with the arrow and lying motionless on the ground. I like this.
The Godson and Lilly are also sat with them enjoying themselves... This sentence needs rework.
Good job with this!
