But are there no gifted children interested in sports? ("no football at weekends")
My db was (I believe) gifted but he was also the table tennis champion at school and obsessive about his violin playing.
And whether there are tired looks and tears surely depends on how much the parents enjoy intellectual discussions with their offspring? If the parents are academics, they might actually feel more comfortable around a child with whom they can have a decent discussion about evolution or the phonetic development of European languages. My dad, a very loving and involved parent, was much better at phonetic development than nursery rhymes.
It took me some time to adjust to ds ("But why doesn't he get it? I told this story to my undergraduates this morning and they got it so why doesn't he? I always used to come home and talk to his sister about my work when she was 6- why doesn't he understand what I'm saying?"). Eventually I realised that it was his sister who was the odd one out.
Sounds more like How To Spot The Parent Who Is Determined That Their Child Will Be Gifted.
I was a the gifted child of an alcoholic and a mother suffering domestic violence. There weren't loads of books around and I think it was quite cheap to raise me actually. No money whatsoever was spent on music lessons. I was just gifted (much good it did me). It all sounds like the usual middle class stuff to me.
IRL I only ever discuss DD2's abilities with DH, my Mum and DD2's godmother. With everyone else, friends and family I'm very non-commital and tend to gloss over stuff, smile and move on.
Because of the school jungle-drums, some other parents are aware of DD2's abilities, and try and quiz me (hoping to compare, or crow, or whatever...) and I very much avoid these parents. I'm very closed-mouthed at school, because I have learned that often other parents have not-nice hidden agendas.
It's these same parents who are braying very loudly in the playground "Oh, look Timmy, is that what book you're reading now. Gosh that's a hard book, isn't it, aren't you a clever boy" ...yeah, right, whatever
In Yr 2, DD2 struggled with some social issues, because her school erroneously decided to move her up a year. It ended badly, and it took time for DD2 to build bridges with her old friends.
If I'm completely honest, I would more than happily lose a few points off DD2's IQ, if that meant she had a smoother path through school.
DS1 plays sports a lot. He is not a keen reader, despite being rather good at it. However, he does like a stimulating conversation. He does ask questions that I have to look up the answers to. But I love it and find him fascinatiing to talk to. He also loves to discuss issues such as Martin Luther King and how he was treated by the people of America and he is then able to link it to the election of Barack Obama. He was 7 at the time.
