Hey, St. Valentine is a martyr of the Church! Don’t ban his feast day!
I remember that it was not fun to be single on Valentine’s Day. Here in Japan, we actually get the commercialized version TWICE. We get Valentine’s Day in February which is girls-give-to-guys only. Then we get “White Day” on 14 March, when the guys give back to the girls. And they give anything white, from white chocolate to marshmallows to diamonds to tissues. (If you get tissues it means the boy you gave chocolate to in February doesn’t like you; you will cry when you learn how little he feels for you–hence the tissues.)
Talk about not fun.
But if you think of it as St. Valentine’s Day, then you can use the opportunity to give something to someone who would not otherwise be thought of on this day.
