Without contributing to the argument of ‘who runs the world’ and ‘who is the man’ etc., let’s just admit, undoubtedly, that there are great differences between boys and girls. These differences are physical and have nothing to do with the brain development of both sexes. Some of the differences we see are these: Boys at 20 will look 18 and act 14.Girls on the other hand at 14, will act 20 and look 18.Girls will spend a lot of time in the salon and come out with something not so different from the previous style they had and boys will go to the barber’s and there is vast difference. Boys do not mind showing up at an event in the same outfit as their friends but girls will feel bad all through. Girls will use 3 hours to make up their minds about a particular dress but in 10mins, boys can complete same process.
Beyond these petty issues listed above, there is not much difference between a boy and a girl. Brain and behaviour development, for example has very little to do with gender. It has more to do with life experiences and exposure.
