That's really sweet... And yes not everyone has a valentine, and that's really okay. I've been single for a long long time, and that never bothered me.. I take myself out, I ate all the chocolates alone, I have a very beautiful & supportive family...
If you don't have a Valentine on Valentine's day; don't be sad. Most people don't have Aids on World Aids day as well...
Be Positive.. Love yourself and take care of the people who take care of you...
