I have a thing for containers. It’s a bit of a fetish: no decor in my home will be complete without some sort of container that I don’t actually use for containing things. Luckily, my mother has the same affliction, so I can blame it on her. Bad mommy. Bad.
Things you can do with an awesome, yet empty tequila bottle (the full bottle having been a gift from my uncle): wash it out, take the paint off with acetone nail polish remover, and display it in the window along with all the other pretty empty containers.
I could use it as a vase, I suppose, but that would defeat the non-purpose. We don’t need no stinkin’ practicality around here.
