What generally is the connection (if any) between an object and your self-image and those around you?

So, for example, in the other thread you mentioned the Thunderbirds and that you watched them with your dad. What if anything might your interest in the Thunderbirds relate in any way to your relationship with your dad?

Or what if anything does your interest in the Thunderbirds (you mentioned that it was weird for a girl to have this interest) say about you?
