People often have the same reaction--they remind us of others we have loved, and we gravitate towards people who will potentiate those same neural pathways. Bobby has always intermingled in my mind with my baby brother, Kyle, who is just younger enough that he brought out my maternal instincts some of the time when we were children. 

Sometimes I wonder if we deal with the loss of a loved one better when we find people similar to them who will trip that same cascade of neurotransmitters. I think it's why we find ourselves drawn to things, too, that remind us of the one we love who has died. 

Each day I invoke my grandmothers in different ways. One grandmother's perfume triggers in me a reminder of her grace and dignity and those days I need an extra dose of grace, I wear her perfume. The other grandmother collected cheap cat, owl, and other figurines, showcasing them in an expensive curio cabinet. So you know I have a small curio cabinet in my bathroom, with one shelf devoted to her figurines and another devoted to my rubber duck collection. Each time I enter my bathroom, grace and kitschy humor are immediately there for me. It's a nice combination.
