Whats the point of taking any chances???... Honestly don't be silly get someone to either come get you or find a different way home from school tomorrow. If you were my daughter the police would have already been called. Just tell them yuor pretty sure it was the same guy, but you don't wanna say definalty in case it wasn't they would rather you call and just let them know then not say anything at all. Not trying to scare you or anything, but if it is the same guy the police would have taken his name so if anything did happen at least they'd have it on record that you spotted him today. Please don't take any chances!!
