What if the most important task, usually ignored, was accomplished by an unremarkable creature? I once saw a cockroach loitering near the kitchen of my grandma's house, and suddenly came up with this idea. Perhaps it was the cockroach which inadvertently accompanied my grandma when she felt lonely. It was ironic for any family members who seldom say hello to our grandma. Thus, I created Henry to strengthen the importance of maintaining a warm relationship with our loved ones.
