I recently learned about White Day. I guess it's even more of a commercial creation than Valentine's Day is now, but all the same I reckon it's a good idea. The more chocolate, the better say I!
Apparently in Japan, it's customary for women to give men chocolates on Valentine's Day, rather than the other way around as it is here. That in itself is an excellent way of doing things, in my humble opinion :D Anyway, then White Day is one month later on 14th of March, where men give chocolates back to women.
We did it backwards (which I guess only makes sense, being on the other side of the world): I gave chocolates to Sarah on Valentine's Day, and Sarah gave me chocolates today! These should see me through to Easter, with care. :D
