OR, maybe the person who came in and asked the question/asked for help is not a proficient computer or internet user and has no idea that they could, or should, search through older posts for an answer to a question. Maybe they should be treated with kindness. maybe answer their question if you can, and then politely inform them that "Hey, by the way, if you have any other questions you can search the forums in this manner for past threads on your topic and you might be able to find a faster answer/solution that way.".
