DEAR ABBY: I played matchmaker for a girlfriend and introduced her to a buddy of mine from work. Two years later, he was arrested for molesting her children, and I just found out he'd had a record for this! She is no longer speaking to me. What do I do? -- REGRETFUL IN OREGON
DEAR REGRETFUL: All you can do is apologize -- which I presume you have already done. Although you were well-intended when you made the introduction, it implied that you were giving him your endorsement. However, you should not have been expected to have done a background check on him -- that was your friend's responsibility as the mother of young children. And she may be madder at herself for not doing so than she is at you.
