invisible

By no means should I be easily missed as I am almost six feet tall with more than ample padding especially in the lower region. Yet, people continually walk into or step on me as if I do not exist. I can be quiet, but this is ridiculous. I even had one woman scream at me for cutting in line when I was standing in front of her for more than five minutes. Am I a ghost? I think not, though I am really pale and can pass for a natural redhead. I just do not understand. Please, see me. Someone...just look, I am here. I exist.
