At my school we do these things called ‘Outside Demos’, where we go to a public place, set up our stuff, then give 30 minute classes to whatever kids are there
Upon being asked to do this, I thought it was going to be super weird, but there were a bunch of kids and we had a good time. It’s amazing how trusting children are and how quickly you go from saying hello, to tickling them and lifting them over your head.
