There are more ways to spread love than just the romantic sort. We can start by not being jerks - it helps, all I'm saying.
You can spread love in zillions of ways - supporting charities, friends, families, or just random people.
Maybe I'm not being clear - what I'm trying to say is, why don't we use Valentine's as an excuse to be loving? To everyone.
Do something nice. Make the world just one little bit better :)
