Mr. Addison, according to Miss Rosenberg, is a very timid man despite his cheerful persona, who basically became a nervous wreck after his parents passed away. Sally meets him in the 103rd apartment on the first floor when he goes to get acquainted with his neighbors. Addison never comes out of his room, mentioning that he's "very particular about his privacy." He speaks very politely and businesslike. The tenants, except for Larry, love his signature tea, which he makes himself.
All that's seen of Mr. Addison is his eyes, mainly. It seems that he has perhaps dark brown hair, dark brown eyes, and somewhat indistinguishable skin color.
