Laundry Counting

I have a weird obsession with numbers. I like to count things and compare relationships between numbers. For instance...my birthday is April 8th. I like the fact that 8 is double 4. Jack's birthday is May 6th. I like that his birthday is in sequence...5, 6. I find myself doing this all the time. Today while folding a load of laundry this is what I counted:

8 sets of pajamas per boy

4 pairs of socks per boy

19 pairs of underwear for Jack.

I'll let you figure out the math on this one...
