What you saw: A young, skinny cub scout crying his heart out as a heartless mother walks ahead of him coldly ignoring his sobs and hiccups.
What you didn't see: A boy who spent the past three days getting angry with his mother over every little single thing she did for him. It was her fault he left his shoes out in the rain, and her fault he didn't do his homework before bedtime, and her fault that there was only green beans and no carrots for the vegetable at dinner. It was obviously her fault that the first two shirts he put on for school were stained or had holes in them, and she was cruel enough to find him a clean pair of socks 1 minute later than he wanted them. So, after days of abuse topped by an extremely bad day of little boy yelling at his mom for everything, the mom goes to pick her son up from cub scouts and (after mom has sat for 15 minutes in the parking lot with 3 kids and a crying baby so that he can have extra time to play with friends) interrupts his game of dodgeball (which had him crying because someone dared to hit him with a soft Nerf ball) to tell him it is time to go home... well, I'm sure you can guess his reaction. Apparently it is her fault that cub scouts ends at 8:15pm on a school night with a 20 minute drive home. So this mom had a very calm but serious talking-to with this young boy and the boy didn't like it. Mom basically says, "You keep apologizing to me for the things you say and do to me. From now on I don't want your apologies, I just want to see you change!" And then the sobbing started.
What you also didn't see the next day (and following 3 days): A son who has been very respectful, loving, and helpful. I've seen him tense up in anger, catch himself, take a breath, and choose a better way to deal. Sometimes parenting means making your child cry and looking bad in front of others, but sometimes it's what a child needs to realize that they can be a better person.
So, to the person who saw my boy crying and gave me a look that said, "Why aren't you comforting your little guy? What kind of mother are you?" I just want to say that you didn't see everything.
