My wife and I get stopped a lot by people commenting on our kids good behavior or cuteness. If they are fat, whatever, we just keep walking like they don't exist. But its usually just old folks being old folks. They will do it at the most inconvenient times, just a total lack of social awareness from the fogies. They mean well, even if they are probably gonna run us over one day because their car is their independence at 80 years old.
