When I was a young guy I hung around with a bunch of guys that like to drink beer - we would hang out at this one bar and shoot darts until we decided where to go - there were a bunch of old timers that also hung out there playing cards - well this one guy was hard of hearing and had an hearing aid - in those days they didn't have those expensive small hearing aids - this guy had something in his shirt pocket and a wire ran up to a hearing aid stuck in his ear - whenever we saw him coming into the bar we would all start making motions with our mouths as though we were talking to each other - then we would watch him as he started turning up the volume on his hearing aid - finally he would get it up to max volume and he still couldn't hear what we were saying - then we would all start shouting out loud - the look on his face was something else to behold - he never did figure put what was wrong with his hearing aid - thought maybe the batteries were going -
