One day when I was taking the Greyhound from Arizona to Washington and was flexing my accents by channeling my inner Irishman to this friendly Frenchman sitting next to me. As far as he knew, I was fresh out of Dublin.
It was only supposed to be for a couple hours until we switched buses, but as fate would have it… all three bus changes I made… there he was. And he found nothing more exciting than talking to his new Irish buddy. Well, I couldnt just fade out of the accent and I didnt want to let on what a weirdo I was by just telling him that it was an act the whole time. So, my only option was to keep the voice up for the entire six hours we sat next to each other.
My voice was so strained after that that I gave up doing Irish accents for a couple months.
