We "do" Valentine's Day but we are also that sickly sweet couple who say I love you daily and we really like each other, too.
I don't see it as a manufactured day, because it is just like any other day to us except we exchange cards and go to dinner. I sometimes get flowers and sometimes I don't. I sometimes buy the husband a bike and sometimes I don't.
I agree with the other poster here who said it is what you make of it.
OOOOH, I do HATE those people who insist that it is the ONLY day of the year to get flowers, or, those who think it is a competition. I know I told you the flower story, right?
