Everyone is shallow in there life time so it is not so much the question of are most GIRLS shallow it is also "are boys just as shallow as girls?" I read a few of the opinions before doing my own and found that some people were saying when a girl see's a guy they always go on there social status or looks, do we really think that it is only girls that are like this. When have you ever seen an absolutely gorgeous guy hanging round with the "bottom of the social status girl" or the "ugliest girl in school"??
to sum this up everyone is shallow and so this makes the question almost impossible to answer because EVERYONE is shallow so therefore every girl probably has been shallow in there life time but it is not on going which means you can not leave your arguement as yes most girls are shallow :)
