I like the idea...hate the actual date on the calendar. On this day restaurants are crowded, stores are decked with heart crap, it's such a pressure filled mess. If dinner, flowers, a signed hallmark card and chocolate is on the agenda than I hate it. If it's honestly a special just "let's focus on how much we love each other and do things we like" day than YAS.
Growing up I never payed much attention to it..the relationship I have had, that lasted through Valentine's Days was nice, though I find the idea of it stupid and more of a money grab. I really don't need a special day to tell me that I love my girlfriend.
