How to behave well around your parents' friends
Be hospitable.
Whether it is an old friend who spends every weekend watching football with your dad or a new friend who works with your mom, you should try to make them feel welcome in your home. Ask them if they would like something to drink when they first arrive.

Options:
+ Put your thermostat up and stay short so that they're not tempted to hang around your house. Create a temperature comfortable to allow them to sit comfortably.
+ Don't get upset if they decline; just be polite and let them know they can come when they want. On the other hand, showing that you are friendly is helpful when an older friend is around, too.
+ Put away your phone or other electronics and make room for them on the sofa if you are sitting in the same room. If you are using the tv or listening to music when they come over, turn it off.
+ If their friends are not available and they invite their parents, then they might be inviting the same people you hope to hang out with. Depending on your age and the size of your house, you might find yourself surprised by how a new member of your household behaves.
