I think that Valentine's Day is inaptly named for what it actually means to represent. The term "Valentine" is derived from Saint Valentine, who most people associate with love in a relationship with a significant other. While yeah, of course V-Day is a day for appreciating that special someone, it's also a day to appreciate the love shared with your family, friends, pets, etc. I think that Valentine's Day ought to be called Love Appreciation Day in order to more accurately reflect the day's meaning.
My own thoughts on the day aside, V-Day is widely seen as a couple-centric day. It can be a depressing day for us singles if we let it. I'll admit, I have no great love for the day of love. However, I don't hate it, either. Honestly, any day that gives me an excuse to get dressed up in heels is at least a decent day. So I hope everyone made the most of their V-Day, whether you're part of a couple or not. For me, my main man is currently my dog, and I had a ball snuggling him all day and feeding him endless Pup-peroni treats (I'm not buying his love with food at all...).
