All you need is love.

Valentine's Day doesn't mean jewelry or kissing, doesn't mean boyfriend or girlfriend, doesn't mean husband or wife.
It means love.
If you're one of those bitter people that can't stand Valentine's Day because you're caught up on being single, stop it. Open your eyes and take a look around. Just because you don't have a date for the night, that doesn't mean that there isn't love all around you. It's just not the type of love everyone is so hung up on nowadays.
There's a reason you're meant to have more friends than significant others at a time. Family's in your life for a reason. You don't need a partner to have love. Sure, the PDA is going to be even worse than normal, and you might not be one of those lucky people carrying around a balloon, a stuffed animal, a box of chocolates, or a flower, but be happy.
And then consider yourself lucky because there are people out there that aren't as smart as you and won't let themselves be happy on Valentine's Day because they don't have a Valentine.

Valentine's Day doesn't mean being in love.
It means appreciating the love that does exist in your life.
