Never show up empty handed
This is gonna sound old-fashioned, at it probably is. But whenever you go to someone's home, bring something. Even if they tell you not to. When you’re young and dating, take the girl flowers. They don’t have to be expensive. Food City has some right by the door. Shake her dad’s hand and tell her mom her home is lovely. As you get older, you’ll get invited to dinner parties. Call ahead and see what they need. Drinks? Bread? If they say “Nothing!” a nice bottle of wine is always nice. And if they are a generous host, they might even open it and share it with you that night. And after a party, leave any beers you don’t drink in their fridge. That’s a little bonus the hosts get for holding the party. Don’t be cheap and leave with it. They will talk about you when you’re gone. And you better have a driver to get you home!
