Background: I have been with my DP for a couple of years now. Whilst we are both intelligent people with careers we are proud of, DP does seem to have a bit of an air of... I don't know, she's definitely more clever in the sense that she knows a lot.
There are huge differences between our childhoods - I was raised in a family of borderline neglect, didn't have any extra-curricular opportunities and went to an inner-city low ranking school. DP went to one of the best schools in the country, had a variation of extra-curricular going on from sport to music, and their family spend a lot of time doing things like general knowledge quizzes, playing board games, etc etc. I left school at 15 with a mix of grades, DP left at 18 with straight A's at the highest level possible.
I suppose I'm trying to figure out how much of a difference the things DP's parents did with her made, vs how I was raised. We are both successful now and I actually have more higher education success, but as I said, DP is definitely still the more intelligent one. If you have a similar type of intelligence to my lovely DP, can you pin it on childhood experiences, is it a luck of the draw, or more of a mix?
