So dh informs me that "do you realize that if they all move out when they're 18 or go to college or whatever, it's going to be a sad 3 or 4 years". Why does he think my pg hormones want to hear that?!? Jerk. I get total anxiety thinking about them growing up and me getting old(er). So at least I got him with "we'll if they're like you I'll have them until they're 30."
You'll have one solid year after Ruby goes away to college before Linus moves back in. Enjoy it. Travel. Then count down the days until you can kick them out again.
I know, I realized just yesterday that Abby will be going to college in only 12 years. I know it's still a long time away, but she's already a third of her way through childhood.
