Lucy to Kate: Can I have that?
Kate: When I'm finished.
Lucy: Can I have it yet?
Lucy: When can I have it?
Kate: You have two options: you can nag me and not have it at all or you can stop nagging and I will give it to you when I'm done.
Lucy to Kate's baby doll: NO HITTING!
Lucy drops baby (on her head!) and runs to the bathroom to consult with Kate: Kate, how old is your baby?
Kate: 1 year old.
Lucy runs back to the baby doll. Baby, you are one year old so you have a one minute timeout for hitting.
Nice to know some of what I say sinks in.
