I do have empathy for people who don’t want to spend their time talking to my children, and I am well aware that not everyone wants to talk to them! I also respect that. My point is really just that, if a child starts up a conversation with you, and you don’t want to talk to them, it’s well within your rights and capacity to politely send them off. You don’t need my help; it’s very easy to do. (And I do stay close enough to notice if someone does brush off my kid. If she didn’t leave them alone after that, I’d intervene.)
