I think it’s just a child being anxious. Bees don’t really wanna sting people, they kill themselves in doing so. But people find them scary so I wouldn’t be surprised to see someone standing still if one landed on them, hoping not to upset it.

But they’re not really likely to land on you cause you’re a bad place to land, and unless it’s something territorial and/or you’re seen as a threat to their nest they don’t really wanna sting you either. (Not sure if there are any bees in that category but there are certainly wasps, which also don’t die when they sting you)
