All girls schools vs. unisex schools

I think that schools should not be seperated by gender because of the social aspects. My parents met in highschool and ow look where they are, MARRIED!!!I think that people should have as many oppertunities as they can to be social and communicate well with others.If girls and boys were seperated by schoolit may be harder for the teachers to teach because girls would talk to much to each other,and the same with the boys.
