Laura and Freddy are cousins, and their grandma is babysitting them for the day.
Although Freddy's mom is the renowned chef in the family, Laura's mom prepared lunch earlier, including potatoes in the oven. But one fell and got badly burnt. Grandma jumped on the occasion to show the kids how to draw with it on a piece of paper.
Sad, Freddy observed:
"My mom would NEVER burn potatoes for me!"
