Gendered summer

Regarding the gender differences in internet behaviour, actually some friends of ours have twins, one boy and one girl. Their behaviour fits perfectly with the above mentioned study. As summer broke, the boy (16 yrs) dragged a CAT cable over to the small cabin next to teir house, basically locked the door, and began spending his summer holiday online, playing computergames. His sister on the other hand, is an avid updater on facebook and as opposed to her isolated brother overall spends more time with friends, both on and off line.
