The first number is a product of our truly random selection (we just moved the cards around and pulled out two cards each - me first followed by him). The second number is a combination of the days we were born.
In the paper the next day, 3648 came out as a consolation prize number.
There is a lesson to be learned here, me thinks while gloating in a corner.
One, lottery numbers really are random. And two, next time I'm pulling out three cards instead of just two. So there!
