I am a whistler. When I am not in the company of others, I frequently whistle and I am very good at it. When I was a little girl, I got slapped for whistling, by my Father, who said it was not lady like.This has never bothered me in the least. I cannot play an instrument, so whistling is my way of producing music.If you chance upon me, whilst I am whistling, you can tell my mood by my choice of tune; Beautiful Dreamer, signifies trouble; Conquistadore , from Carmen,means I am busy working and Vincent means I am relaxed. Now there is the rub. No matter where I am, if I whistle Vincent, cats coming running from all over the place. If I am in the garden, strange cats appear. Now, the thing I want to know is, are they drawn to the pitch in that particular tune, do they like the song, or is my projected emotion reaching them? No other tune has this effect. Go figure!!
