Suddenly crushing on a childhood friend?

So when i was young there was this boy (a little older than me) that was very close to my family so i met him sometimes. Haven’t seen him in years now by the way.

I have no idea why but im just suddenly attracted to him, All i can remember is that he was very sweet and used to show me stuff and impress me, he was extra kind to me for some reason.

Could this mean that he used to be attracted to me?
