The math may not be accurate, but the statement is true, nonetheless (as long as you read your dates in American style, anyway).
They shouldn’t have
Diane and Jeffrey both got me things I wanted for my birthday, but I suspect they really shouldn’t have. Jeffrey gave me Iron Chef: The Official Book, and Diane got me a subscription to the Sunday New York Times. Both will keep me busy for many happy hours (and the subscription will require an increase in the household pencil budget, especially at the eraser end!).
