Btw, there's another Valentine's-like day on March 14th. They said it's white-themed which the receiver of gifts/chocolates/letters on Valentine's Day(14th February) have to reply to the sender.
I kind of sick to celebrate this kind of day(no hard feelings), and thank goodness I just received a few letters and a box of ferrero rocher. Now, I having difficulties to reply to the sender, especially to the anonymous. >_>
