jsn,
In kindergarten I joined in "he" or "hide and seek".
Four years later, I joined in a skipping game called "salt and pepper." It became quicker after the fourth jump, with girls whirling two ropes.
A hopping game where the pebble had to land on the 1st, 2nd and 3rd chalk square and so on. Completely forgotten the name 
At 10 I started tennis lessons. I especially enjoyed sliding toward the ball on a clay court. 
Would you think it was odd if a younger person wanted to befriend you?
