<human>: Can you provide a brief rundown of the text in within 3 sentences?

I get on well with my dad, we work together and he's basically the model for a good parent. We do fall out once in a while but usually its clear that one of us was in the wrong.

I have a pretty unusual visual condition which causes my eyes to move around constantly without my control, it causes me to have pretty poor eyesight and gets me some weird looks from people who don't know what it is. I do my best to present myself in such a way that i don't draw attention to it and also to make sure people know that there isn't anything wrong with me other than my eyesight (some people have assumed i had a mental handicap or something like that).

Anyway, he told me the other day that somebody we both know asked if i needed a guide dog. I don't want to know who it was so i can confront them, i just want to know so i know how i can make my more clear in future to other people. He point blank refuses to tell me, even after my mum and i trying to convince me for an hour.

Am i  being naive or immature in thinking he should tell me? I really feel like this is something i should be allowed to know but i don't know how to make him see that.
<bot>: My dad knows who said something stupid about me, i want to know who it was so i can act differently in future, he won't tell me.
