#1. Allow the two of them to hang out with family, whom we don't see as often as we'd like. Mel's family had been wanting us to come out, especially since we missed the mini-family reunion last month. Plus, we'd been wanting to show off Peanut, since she becomes more awesome by the minute.
#2. Allow the two of them to actually see and interact with humans. Rob has been working some pretty long hours of late, and this week (and month in general) was going to be no different. So while he was putting in 14-16 hour days, why not let them have a little fun?
They had a grand ol' time with Lew Dog, Tauna, Emblebee, Bebo, Jen and the girls. But, much to Rob's surprise, Penny changed immensely while they were gone. First of all, she went from crawling a couple of feet to moving constantly around. Plus, when she left, she was almost bald, and now look at her! It's crazy. You're away from them for one week and all of a sudden they're off to college or something.
She leaves for a week and all of a sudden she's Rapunzel.

Robot and Frank are so glad to have them back, even if they have a hard time recognizing them. So let that be a lesson for you, don't let them out of your site ever again.
