I have a hugger who has trouble knowing where the line is. It's hard for me to get her to understand the difference between who she can and can't hug, when someone I have explained as not falling into the appropriate category decides to offer her a hug. All of my work is undone, and while they obviously meant no ill will, it's extremely frustrating for me.

It's lovely of your daughter to let him hug her as long as he wants to, but he'll wonder why the next person he hugs doesn't want to do the same.
