Did you have any imaginary friends as a kid? What were they like? Do you still think about them as an adult?
I didn't have any imaginary friends, but I used to have stuffed animals who I'd give personalities to and have them enact stories in my head. I used to consider them friends of mine too, and would have them watch TV with me and generally felt comfort in their presence. I kept them up until the age of about 12 or 13. Once I started middle school, I tried focusing on my relationships with my classmates and friends. Still though, I've always been introverted and prefer being by myself.
