I will wave to anyone. Sometimes though I will wait until they wave first. I dont know why that is. I waving and no getting a wave back. When I had my Jeep Wrangler people with other Jeeps waved all the time it was great.
Maybe someone can explain though why the wave for motorcycling is the low wave?
... to everyone but only on official occasions from thebalcony, carriage or limo .... after all one doesn't want to appear distant from ones subjects, does one?
