I can't point to anything I've accomplished as being entirely independent of the advantages my parents gave me; what makes my circumstances any different from Patrick's?
Let me try to put it this way:
I want't born stupid, but my family situation was pretty lousy to begin with (father violent and alcoholic), so my mom divorced when I was 6 and life was pretty tough for her, my sister and myself until I got to high school.
But I did eventually get to high school. There it got tougher, the first year I tried to learn as much as I could, pretty much scored straight A's, but was despised for it by my class mates, failed the second year, dropped out at 17 after failing again. My home situation steadily worsened during those years and at some point it looked like living with my dad would actually be the preferred situation.
Bad mistake... Anyway, by 17 I was working for a bank in the mailroom, eventually someone in the IT department gave me a break and I've been doing pretty good ever since.
And now for the but bit :)
So, even if I didn't have oxford educated parents, I know that I could not have matched you, even if I had wanted to.
The reason for that is simple, see, in spite of my 'rough' (nothing compared to some people in this thread though) start in life I know fairly well which bits I got through persistence and which bits because I got lucky.
I chalk up your living circumstances to luck, just as Patricks presence in the pool that day was luck, just like me getting a break.
So Patrick can take 'credit' for doing what he did, I can take credit for making the most of that one break I got and you can rightly take credit for the things you've achieved.
Circumstances made them possible, but the hard work that went in is what you get to take the credit for. Yours was a lucky situation, but plenty of people might not have made that much of it, myself included. I know my limitations. I also know what I'm good at :)
Everything in life is one part circumstance, one part what you do with it. So, you achieved well over and beyond what most people born to two educated parents would have achieved and I think that's what you are being recognized for.
People save other peoples lives on a daily basis and it literally is the most natural thing in the world. I prefer to think that anybody would respond to a child in danger that way.
