Etiquette, visiting another house?

[Mendalla]

I think it depends whose house we are talking. I'm going to be a lot more casual about etiquette in my son's place than my aunt's, and in the home of family than in the home of a friend or co-worker.

Be respectful, polite, and clean. Don't wear out my welcome by staying over too long.

However, I think these apply to all.
