Bring food. A bottle of wine is pecrfet. It's not a gift, but you're still bringing something. Look online for recommendations of wine in the 15-20 dollar range (that way it's not like you're spending a ton, and it's not like you got WHAT kind of wine?! ). Once I had a party and I told everyone to bring wine. So we had one bottle per person and then we drank it all yeah. I like wine.
