Where are the girls??

Today, i went to deposit fees in Ishaan's school. The session will only start in April, but the fees is due now. This was post school hours and it was a pleasure to see children playing all around - in the corridor, in the field, where 2 soccer games were in session, and on another side, general pushing and shoving games.. all in good fun. And then, just as i reached the building, it struck. Where are the girls? Why are no girls playing in the fields? No badminton, no basketball, no soccer (i m a sucker for Girls soccer) , no tennis.. nothing! not one girl?
I paid the fees and on my way out, stopped by at the reception and asked "Where are the girls? Why is there not a single girl out there playing? Of any age at all?" The answer was rather non commital - they are probably in the classroom or in the library or wherever they want to be. This is not the sports period. So every child does what they want to do at this time.

Well..... not ONE girl interested in playing? Thats REALLY dissapointing. What is going on here?
Is it the peer pressure? The jeers from the boys? What is it about sports that keeps girls away in a well to do(even if i say so myself) public school in a well to do neighborhood? Even girls in slums do physical play. What is going on here?

What happens around you? Do girls do active physical sports? I think its CRUCIAL for girls to be athletic and active in sports. it gives physical confidence like nothing else does. And it doesnt even have to be formal sports - just physical playing - running, climbing trees, racing, jumping contests, gymnastics.. anything at all.. where are the girls??
