Not done Sir, but doing.

"A teacher said of one 10-year-old boy in her class that his performance was generally poor, with him being just about able to write his own name; but she went on to add that this was not just because he was not bright or able but because he could not sit still. What is important about this remark was that it was of a type which was fairly commonly made about boys but never about girls. Poor performance is not taken to be an indicator of necessary lack of ability in the case of boys. Rather, they are active (just can't sit still). By comparison, it was common for girls who were doing extremely well to be described as not bright. 'Her hard work gets her to her standards' was a typical remark. ....This is not a simple matter of bias, but one point in a complex and gendered history both in relation to Reason (the Ratio) and the work/play dichotomy in which reason was inscribed in modern psycho-educational discourse."
