Cate: Mom, how old is Dad?
Me: 42.Cate: Wow, that’s a lot! But not as big as googolplex!
Me (trying not to laugh): No, definitely not as big as googolplex.
Cate: And not as big as Graham’s number!
Note: Cate and Bree are quite interested in the concept of googolplex and so Greg had recently told them about Graham’s number (the largest specific positive integer ever to have been used in a published mathematical proof.) I guess she was paying attention.
