Dear Ann Landers,
A few years ago, you printed warning signals to determine if a mate is a batterer. I want to say thank you. You saved my sanity, possibly my life, and gave me the strength to leave my abusive husband and regain my self-esteem. Please print those warning signals again. With luck, they may save someone else. -- Grateful in Fort Wayne, Ind.

Dear Grateful,
Obviously, that column made a strong impression on you. Here it is again.
