I always think of emotional eating as what you do when you are stressed, but for me it's more likely to be either boredom or happy times.
Once or twice in my childhood, my dad took me to the movies and bought Jordan Almonds. They are those pastel candy coated almonds that are sometimes served at weddings.
I liked them pretty well, but I hardly ever buy them. When I do, I think of my dad. I eat one or two and then save the rest for another day, and stretch out the memory of Dad holding out the box of candy and offering me some. That's a happy memory. Minor, but happy.
