Just go find all the pictures of famous people picking their nose or what ever. That is what happens when you have cameras everywhere. If someone does not like you they will only show you picking your nose, scratching your butt, and other disgusting things. Then they will put them all over your school and tell all the girls to never go out with you. How hard would it be to get a date no matter how nice you are? Now imagine if they showed those pictures to girls that do not even know you all over the State of Texas or the whole country. One picture can do a whole lot of damage. There is nothing wrong with picking your nose or scratching your butt you just do not want people that do not like you to get them.
Good answer!!
