notebooks

sooo...i finally went to go get notebooks for class today. later i was sitting in class and i was looking at the little calendars at the front of my notebook. they spanned the years of 1999 to 2002. when i came home and looked at my other one i had bought, the years were 1995 to 1997. since there's really no reason to put an out-of-date calendar anywhere, i can only assume that these notebooks were produced before the dates on them. that is very, very strange. i wonder what else we buy that could be almost 10 years old...
