Don't disrespect other peoples property, that means treat their stuff with care and don't ruin it and don't abuse their furniture and their items you use, do not leave garbage around in their house, always take off your shoes if they are wet or muddy, always hang up your wet towel, always keep your clothes picked up.
Don't call people names, don't put them down, don't abuse them just because you think they are dumb.
Don't push and shove people, don't cut in lines.
Don't give out unsolicited advice.
Ask questions about what they would like you to do if you are not sure how to act in a situation.
Do people favors if they ask you to do something, do not take this as a question.
Sadly people will never see this because all this stuff means nothing to them to indicate you care.
