Actual reader mail. Dear Dr. Sadie, Bless you Doctor. I wrote you back last July and asked you if I could expand my grumpiness beyond getting up in the morning. I took your wonderful advice and now there isn't a neighbor, fellow employee or friend that's not fed up with me. You have given me a new existence and once I get out of this lousy jail I'll let the rest of the world know just how annoying I am. I owe it all to you, Sadie. If you ever need a testimonial, call me. Signed, An ol' stick in
