In the mornings, when Mom's still in the bedroom with Abby, sometimes Dad closes the bedroom door. Usually I protest against this horrible injustice to no avail. But today I tried a new tactic: I asked nicely. "Daddy, o(pen) dee do(or) p(l)ease: Mommy (is in there)!" Amazingly, it worked. Wonder if I'll remember how to do it tomorrow.
I also tried "Open the door please" on a can of wooden blocks, but Mom didn't understand. After a few tries I switched to "Open the blocks". She's still learning, so I'm flexible.
