Because they can burn their fingers off. 7-year-olds aren't the most responsible of people.

What bothers me even more about this photo is you can clearly see the black spots where she's holding from where it was heated up before. That alone should tell you not to hold that spot.
A good joke takes 10 years in an old cherry barrel to really ripen and come into its own.
