My own kids had friends like this, especially youngest son.
Like the others said, I treated them just like my own. Turned
out that they actually LIKED to clean and cook yummies and
walk the dogs. Their mothers smugly announced that their
houses were always clean...of course they were. Their kids
were always at MY house, and I got to know those marvelous
young men better than their parents did. Even now, in their 40s,
large men will grab me and hug me and ask about all the family,
tell me about their own kids, all the while their wives stand by, tapping their feet!!
HA to them!! I LIKED them and still do.
