valentine's day how far is too far?

For valentine's i've been hearing alot of people's story's and it has lead me to wonder how far is too far? So i've been thinking of different valentine's day gifts. Like box of chocolate's i think is fine because it's candy, it's amazing! I think that me running up and singing and valentine's day song or somthing like that is too far. I think things that are fine for valentine's day is maybe a box of chocolates or a dinner or maybe even a flower but not all three!
