Sideways: I like how wine continues to evolve, like if I opened a bottle of wine today it would taste different than if I’d opened it on any other day, because a bottle of wine is actually alive. And it’s constantly evolving and gaining complexity. That is, until it peaks, like your ’61. And then it begins its steady, inevitable decline.
HHG2G: Vogon poetry

Sideways: Xanax
HHG2G: tea

C’mon y’all, jump in if you know any others…
