Not as in a nasty way , but a really loud talker ?
With mine we can be sat together but he will speak to me in a loud voice , or if he really wants to tell me something , he can be loud . Same if you are out , he can be shouty then. I tell him I am next to him & can hear but he doesn't seem to have a quiet mode . Don't think he has any hearing problem. Anyone else have a loud one ?
