The Y Chromosome

The Group: Three boys, one girl
The Game: Very detailed, nuanced game of Superheroes. Lots of "pretend I can fly and then I fly to take you to the doctor and you pretend to be sick but then you get better after I fly you to the doctor then we fly back home...no, fly like THIS".

Mom picks up the girl.

The Group Now: Three boys.
The Game: How many times can I push you down? OK, now YOU push ME down! Ha! That was awesome! OK, do it again! Now, how far can we jump off the playscape? Oh, come on! Farther! How hard can I kick you? What? Come on, Moooooom! We're JUUUST punching ears!
