The saving of empty beer and liquor bottles is a strange college phenomenon. I bet most of you college students reading this right now have some empties on a shelf in your room. Everyone knows how much college kids like to drink, do we really need to display it? It's a good thing, though, that this trend stops after college. Wouldn't it be weird if your parents had empty wine bottles up on their bedroom wall?
