Clowns don't bother me. I never wanted to go to the circus because even as a kid, I knew it was wrong to make elephants sit, roll over like a dog, and do "tricks" for human entertainment. I went ONCE....but not inside the tent. I went to where they were feeding and washing the elephants but I couldn't get close enough to them to tell them I was sorry they were chained at the leg and that I loved them. Then Ma dragged me away because I started a scene by crying.
I was in my 30's when I burst into tears at Barnum & Bailey's, when their famous really old elephant (whose name I can't remember) came into the ring loaded with circus gimcracks. He was WAY larger than the others and he looked so old and tired and the indignity of the 'costume' and the situation just killed me. He passed away shortly after that, of old age, they said.
That being said, I LOVE the circus. The fire eaters and the tightrope walkers and the human cannonball and the smart little dogs, not to mention the candied apples and the peanuts. The smaller the circus, the better--it's all right there at your feet in a two bit traveling circus tent.
Back to the CLOWNS, though. People are afraid of clowns, I think, because of their "mask." Their comedy is slapstick and if they're really good, mime. Kids are the ones who find that the biggest hoot.
