and so is XMAS DAY, mother's day, father's day....and if they could, invent also brother's day, sis' day, uncle's day, auntie's day......
everyday is a "day". LOL!
and teacher's day is headache day for the wifey! kids wanna give something to their teachers (plural hor) and the wifey would be bz buying and wrapping stuff....and my pocket would also be very bz draining out $$$
