Kids can be cruel, mobbing, excluding etc. School is a though place. People become better the older you turn, less judgement and more acceptance but we struggle moving past our childhood traumas and don't realise the Change. "Those who care don't matter and those who matter don't care." Not everyone will accept it, that's ok. You don't need to befriend everyone. Confidence is a strong partner, if you stutter do it with confidence and you'll be alright
