I think I am his older brother or something along those lines. He is very social and loved by all humans but he shows more affection towards me and his real brother. They meet less than once a year because my sister moved far away, it is always interesting to see how much they still love each other (they are now 11 and have lived longer separated).

He calls for me sometime either for help with something or because he wants to be with me and can't find me. But he doesn't feel needy like a little kid toward their parents as long as I haven't been gone for long. He do need a lot of love every day.

I don't think he sees me as a parent but we have a very close relationship and mostly understand each other and he trust me a lot.

He is very polite when he is not at home, like waiting by the the food bowls without saying anything (for example when my parents takes care of him), at home do he come and ask for food and sometimes leads me to his bowl so it really feels like a kid who is reserved around other ppl when it comes to needs but is very social, outgoing and not shy at all when it comes to other things haha
