Sssuuummas ssssuuummas ssssuuummas ssssuuummas
I talk/mumble to myself a lot. Especially when I am tired, anxious or irritated. It is usually some gibberish like "sssuuummas ssssuuummas ssssuuummas ssssuuummas". I wonder if other people notice me doing this. Is this just a nervous habit, or am I out of my mind?
