I hear lots of people say that Valentine's Day was a "holiday" created by capitalists as a way to have something to make money on between Christmas and...well, summer. I'm not sure I entirely believe that, but in case it is, let's protest and bring the love back into Valentine's Day.
This Valentine's Day, let the people you love know that you love them. Look into their eyes and tell them as sincerely as possible that you love them with all your heart. If you feel you have to give a gift, make a card by hand. I promise you that for all but the most superficial of people, this will mean more than anything from Hallmark.
And if you really must give someone a dozen roses, I have some for free right here.
