Happiness is a tricky thing. It’s quite the elusive noun because it’s not tangible, like a xylophone. It’s not visible, like a shadow. You can’t even hear it, like a Carpenter’s song.

Sure, a big ol’ dose of it can be caused by your recent Anthropology spree/Himalayan trek/supafly booty call, but often we just coast along, somewhat dis/content and try to grasp at that greased pig we call happiness. Thankfully, there’s Happy Hour. I don’t know what genius…
