Intervene.
Walk by and say nothing.
Take a different route home.
You walk by, trying not to draw any attention…it doesn't work.
"Hey, you! Yeah, I'm talking to you, kid!" One of the kids (who must be the leader of the gang) walks up to you. "I'm short a few coins…do you have any Gold you could spare?"
No Gold, huh? That's too bad. That is a nice pair of shoes you have there. I think they might fit me, mind if you take them off for a moment so I can compare?"
You take a look at his feet. They clearly won't fit him.
