"Valentine's Day was a holiday invented by greeting card companies to make everyone feel like crap." This line, from Eternal Sunshine of the Spotless Mind, I can appreciate. If you've never seen this movie, you should watch it for the first time on Valentine's Day. Trust me, you'll never look at the holiday the same ever again. In fact, you'll never view any of your relationships with anyone the same ever again. If you've already seen it, see it again! On Valentine's Day. Watch it alone or with your significant other. Watch it on your first date (although most of us can agree that Valentine's Day, with all of its expectations, is probably a terrible day for a first date). Afterwards, you should talk about it. The best conversations I've ever had have occurred after watching Eternal Sunshine. It's a love story told in reverse and it's about love and loss and sparks interesting ideas and contemplation.
