Well, for the safety and protection of the kids, DO NOT USE THEIR REAL NAMES OR LIST THEIR DISABILITIES! Other than that, tell use why, when, and how the kid made you smile!
One little girl was riding in an English saddle for the first time, so they put a belt with loops on it on her so the sidewalkers could hold onto the loops. It was like Christmas morning for her! She was SO excited about the belt! She'd sit up there with a smile too big for her face on and blurt out "THE BELT!" and laugh hysterically!
One little boy I always seem to lead for and there is a sidewalker who always seems to sidewalk for him. The sidewalker will quiz him deeply on what he learned in school and--to be honest--I learn more school-related things in that half hour lesson than I do in a week of school! Also, the same little boy has a friend. Who is a girl. He gets all red when we tease him about it :)
So, how about you???
