We recently worked out an exchange with the Bratling. She comes over about once a week to visit & stays the night. It's nice to have somewhat regular time with her. Last week, we dug up the spare key for her.
After she drives me to work in the morning, she goes back to the house and does some cleaning. It's nice to have the extra hands. D and I seem to have a hard time keeping up with everything. So we get something that helps us out, and she gets something she wants, too.
I have to say... I really like the idea of her being there. In my home. Not far, far away, but just right there.
