It is a little hard to see, so here is the transcription:
To Dad (picture of car and tire). Dear Dad, Come downstairs and watch High School Musical 2 with me and mom. Love, Michaela
To Mom (picture of flower and heart). Dear Mom, Come downstairs and watch High School Musical 2 with me and dad. Love, Michaela
And for her loving sister: (Heart with a line through it, a la a "no smoking" sign) Hi Poop. I am sticking my tung out at you. Ha Ha Ha. (Picture of Michaela with her "tung" sticking out and squinting angry eyes and Jenna crying.)
Lovely. And sooo first grade.
