Egoist

[portokalos]

The man who is making circles around himself.

[Slava]

The Dr.'s treatment is here, with some interesting commentary.

As to drawing circles about oneself, my father used to say thusly: "You've drawn a circle about yourself to shut others out. I've drawn a bigger one to include you." Or something along those lines.

[LukeJavan8]

A circle on the floor or ceiling, containing a pentagram,
usually contains a demon, at least in the demon and
vampire movies.
