I had a friend at boarding school who not only stuttered but, as he himself admitted, he needed his RRRRs rolled, a statement which always gave much merriment to all but my friend. Us brats always knew him as per, per, per, per Poll Gwave Bwown, or Per for short, perhaps Vaughan remembers him? I was to meet him many years later, his elocution and Rrrrrrs rolling lessons had obviously worked wonders. Was I tempted to revert to stuttering myself, that always started him off! I must have been a horrible child!
