By Day - or night, depending on when the phone rings: I clean drains and deal with people with clogged drains, all sorts!
By night - I learn stuff from books or TV or in person and listen to good music.
My yichus? I am a shining example of a descendent of the proud, but not too proud folks from ..somewhere in Eastern Europe, wherever they let the Jews live. Mailmen, lawyers, El conductors, teachers, and other fine examples make up my illustrious forebears.
