I am 13 years old I would be alone with a cell phone with my destination about 1 1/4 miles away. It is 80 degrees full sun and I am wearing shorts and a t-shirt, I would go to an outdoors mall (With the shops in their own buildings) to walk around.

Should I go for a walk?

Let someone know you are leaving and where you are going. If theres no one home call someone, like a parent or sibling and let them know you are leaving the house and exactly where you're going. If they advise you not to go, stay home and play in the backyard(:

No. Stay home on the Internet and rot your brain like the rest of the kids your age.

yes,go for a walk,but let someone know where you are going

Ask for your parents' permission first.
