Nothing. I'd completely forgotten about it honestly.
Does anyone find that it's way more fun to spend Valentine's day with your lonely friends than it is to spend it with a date? My favourite Valentine's Day memory is of being about 15 and going to school and all of my friends making each other really shitty Valentines or printing out and giving each other those stupid tumblr meme valentines like pic related because none of us were getting/giving any roses out as the school had this program where if you gave them $2 they'd send your crush/gf/whatever a rose and card for you while they were in class and typically it was only Stacies and Chads getting and giving them.
Shit was fun. I gave my best friend a valentines that had a poorly drawn picture of a guy pooping heart shaped turds into someone's mouth on it that said 'Hope You Get Lots of Chocolate This Valentine's Day'. He loved it.
