The thing is - I can't imagine their awesome relationship will be much different as adults. They make each other laugh. They look out for each other. They share everything. They occasionally bug each other, but all is quickly forgotten in a game of pirates vs. monsters.

The only thing that will change, probably, is that instead of late night gab fests from beds on either side of the same room, they'll have late night gab fests over their cell phones.

Knowing how much Bill and I love our own (and each others') siblings, I am pretty excited for them.
