I was walking home from the town yesterday, with my dog lead in my right hand and my PV in my semi paralysed left hand as I am wont to do. My left hand "clutches" well, no trouble holding anything in it - nothing will ever fall out! So I carry my PV there - it hides the annoying stroke position and people think I am carrying something instead of walking "funny". I met someone I hadn't seen for over a year.
He greeted me and then exclaimed "What a wonderful dog whistle!" indicating my PV . I was really taken back and it seemed soooo amusing!
He got an excellent lesson on vaping.
Dog whistle, my foot!
