by Karyn Hall , Op-Ed Contributor, August 19, 2015 I have a mini-battle in my house at the beginning of every school week over how many times my son can buy lunch in the cafeteria. He loves to buy lunch and would do it every day if I allowed it. I always assumed it was the experience that drove his interest: standing in line with friends, making choices, charging his account. One week I got the real scoop: “Mom, I’m not allowed to eat with my friend because he has allergies,” he told me.
