Educate them Ignorance is dangerous. Can do damage if left unattended. Educate your friends If they know how you feel about it and still laugh when you stutter then the problem isn't educating them it's undervaluing yourself In which case make new friends and cut ties Life is short, take it from someone lucky enough to be in remission Our time is valuable So too our words Especially 'our' words So spend them where they are appreciated and where possible nowhere else Good luck ✌️
