DEAR ABBY: Fifteen years ago, my partner and I moved to a new community, befriending a neighbor whose initial kindness and generosity impressed us greatly. When the neighbor learned I was unemployed, his influence enabled me to secure a position with his company. In a professional setting, however, the neighbor revealed a personality that was manipulative, condescending, backstabbing and mean-spirited, often reducing colleagues to tears with his profanity-laced tirades.
