I have red hair, now quite happy with it, but hated it through school years, as I'd constantly have friends going 'ra raa... bla bla.... red hair, ginge, gross, don't you think so Berg.. oh, well, I mean, not you obviously, you're not a real ginge, you've got brown eyes so you aren't all ugly and pasty...' etc etc....
Of course, all I get are compliments these days, and comments such as 'wow, is that your natural colour etc etc....' Kids eh?
But, for that reason, I have to admit I really did not want either of my boys to have red hair, purely because of the flak they might have to deal with as children. One is very dark like his dad, the other quite fair, so he may well get a bit red-headed as he gets older.
There is NOTHING wrong with having red hair, but it's a bit of a pain as a child and would not wish it upon my own children for that reason. But, I guess, if not red hair, then it's being too fat/too skinny, or speccy, or spotty, or something else that marks you out as a little bit different....
