My theory is that if people had any idea what the other urglers looked like
it would help towards less misunderstanding.

I don't know why I think that, but I think I'm right. I always think I'm
right. If I see someone in a pub covered in tattoos and wearing rigger boots
I will address them differently from someone wearing a twinset and pearls.

Here is a Marvo pic. It features neither tattoos nor pearls.

I don't normally dress quite like that, I'm usually scruffy. You may guess
why I am wearing whatever it is in that pic.
