Definitely being pretty presents you with more opportunities than otherwise. I've noticed beautiful children often grow into adults with lots of confidence.
Someone once said to me 'people are nicer to good looking children' and that was certainly true in my experience. Thinking of my very pretty little friend who got freebies in the sweet shop when I had to pay.
If you were pretty & well turned out when little in our school children would be drawn to you. I was permanently ill it seemed and rather unfortunate looking. I didn't get the 'visible' school parts for this reason, these were reserved for the pretty kids.
I've told the story before of the plain girl who could sing and the beautiful girl who got the star part in our musical school play. The beautiful girl couldn't sing at all, a bit of a flaw for a musical. No problem though as the unfortunate looking one sang for her off stage!
My friend's daughter is worshipped for her beauty it seems. It's ridiculous, people comment on it literally every day, the little girl know says 'I know' in a bored voice when people tell her how pretty she is. Her sister is largely ignored when they out in public, people don't realise it but they are drawn like magnets to the beautiful little girl.
If this little girl grows into a plain adult woman I'll bet she'll still have the advantage of confidence that has grown for these superficial reasons in these early years.
There's a line in the movie Shallow Hall (not terribly high brow but bear with me) that beautiful girls who were 'ugly ducklings' are 'easy' as they don't believe they are good looking. I think that may be true to a degree.
I think of Cheryl Cole. If she was less pretty she'd never have gone as far as she has, although teenagers I meet deny this is why she's on TV. It's apparently because she's uber talented and hard working. Perhaps but with the looks she had she had more life choices than others on the estate in Newcastle perhaps.
