Decaf coffee sounds like sex without nerve endings.
Seriously, I don’t even understand the point of decaf coffee. It’s like nicotine-free tobacco. Or sugar-free Sugar Babies. If you’re going to do something, then do it. Don’t go through the motions with some neutered substitute.
I’m a coffee drinker, but I’d be lying if I said that coffee tastes that great. It’s the pick-me-up and/or pain relief properties of caffeine that make it worthwhile. You take that part out of the equation, then why bother?
