You wouldn't force a girl to date you because you know it's not rational. You wouldn't force kids to play with you because it's not rational either. Simple as that. Just because somebody thinks it is actually rational doesn't make it so. The kid wasn't rational at all, if anything his behavior was completely irrational
Yeah we wouldn't, because we have empathy and understand other people. If you can't conceive that people can even like each other at all then all their behavior just looks like some complex status game to you. There's nothing irrational then, with your limited understanding, about coercing a behaviour that you want, any more than it would be irrational to force an exchange in chess because the Knight didn't "want to" move.
