LP is a genius. I know, I am biased, but the evidence is pretty clear.
This morning I was washing the dishes and remembered that there was a sippy cup still in our living room. I turned to LP and asked her to go and get me the cup. Two seconds later she was back at my feet, cup in hand.
Then, as we were climbing the stairs, I was pulling up some lint from the carpet (fancy housekeeping, right?). When we got to the top of the stairs, LP saw the ball of dust bunnies in my hand and grabbed it. I told her it was garbage so she walked into the bathroom and dropped it into the trash can.
I know, these are not big tasks. But it is truly clear to me that she understands everything that I say. Of course, a lot of time she purposefully ignores me, but that is par for the course.
