DEAR ABBY: I have an issue with my father and don’t know where to turn. Dad is in his early 80s and — aside from poor eyesight — he’s in good health. I’m concerned because he has developed an unusual habit. He likes to look through the dumpsters behind the grocery store. Initially he told me it was to get old produce for compost in his garden. But I have learned that he eats some of the things he finds. I have tried telling him this is dangerous. He could cut himself digging through the trash or get food poisoning.
