Valentine's Day is a big deal because we live in a capitalist country where retail stores make a fortune off getting people to buy useless crap through advertising. Then they bill it as a holiday so that you are a bad person if you criticize it according to them. Like how at Christmas if you aren't willing to go in debt buying everybody stuff you are called Scrooge or how if you don't shell out dough for July 4'th you aren't patriotic etc. etc.
