Happy Valentine's Day to you too~
My family doesn't usually do anything much for Valentine's, but it's a tradition for my dad to buy my mother and I some chocolates and arrange them in outlines, like a cat or a heart or something like that, on our places at the dining table. I also remember, when I was younger, there were larger gifts like giant stuffed pink unicorns with balloons tied to them. When that happened once, I woke up early in the morning so all I could see was the silhouette of an odd form, and being a little kid, it scared me so much x3
And Valentine's day is important because you can show another person how much you appreciate them while not being embarrassed like you'd usually be, since everyone's showing the same affection to someone special (for me, though, I don't have any crushes/secret admirers, so I usually only let my friends know how much I care about them and love them in that friend way)
