Parenthood 101

Abby had pealed a hard boiled egg and left the peel on the floor in the living room. I asked her to please pick up the shells. She came in the kitchen, where I was and declared that she had picked them up. Then I asked if she had put them in the garbage. She just looked at me like "Oops, I forgot", she ran back into the living room and gathered the shells from off the piano bench. I just assumed that she knew what to do with them.
I forget that I have to be specific with kids, especially 4 year olds.
