<human>: Can you condense the text into a few key points?

I was adopted as a teenager by an aunt and uncle who took me in after I spent years shuffled around, homeless, etc. With the exception of situations like this, I don't think of them as anything but my "real" (they certainly aren't holograms) parents.

People that knew me before I took their name still insist on addressing me by my old name. I find it rude and offensive. Correcting doesn't seem to work. Worst of all, I've had people bust in on conversations where I'm introducing myself and say things like "but his real name is -insert former name here-."

It's made more complicated by the fact that a) I live in an area where there are no more than a few degrees of separation between any two people and b) the thought of people making comments like that to my kids (should I ever have any) makes me mad.

Short of cutting throngs of people off (I already have some, but for other reasons) or changing cities (which I don't feel like I should have to do), I'm not sure what else to do.

I'm hoping someone else who has been through something similar has some guidance or perspective I haven't thought of. Posted from a throwaway.
<bot>: Wondering how to deal with people who insist on addressing me by a name I don't go by anymore (and haven't in a long time) after being adopted.
