Daddy always spoils me on my birthday. He buys me a lot of presents, and bakes my cake himself. This year I tried to blow all of the candles out in one go, but thirteen is a lot, and one was left flickering, the flame dancing in front of my face. My dad leaned forward and blew it out for me. He's my best friend but a good parent too, he would n't let me skip bath or brushing my teeth, even though I wanted to since it was my birthday. Mommy used to wash me but daddy took over when she died, and he does a pretty good job. He makes sure to get me clean everywhere. After that he tucked me into bed, and he even remembered to leave my door open a crack since I do n't like the dark. I love my daddy.
