Toddlers!!

My daughter is the cutest thing, i think, and so many people think she is so smart for her age. She hangs out with adults more than kids her own age and she acts like an adult alot also. She still loves being a toddler and playing but she talks like an adult (like she knows what she is talking about) Then a couple days ago she did the toddler thing. She's coloring in her coloring book and i'm sitting next to her looking at things i have to do for school. I spaced out for a minute and she went to work. First off i have white walls, (do you know where this is going? :) ) Yup, blue crayon all over my while walls and it won't come out. I was told a magic eraser so i have to try that and hopefully it will work. If not, i will have to repaint my walls and i dont really wanna do that because its already freshly painted by the last owners. Wish me luck on getting it off!!
