Cause and Effect......
Sometimes if a person doesn't give enough information when they post a problem, the person who replies starts at the beginning, and quite correctly,(from a tactical standpoint), proceeds on the assumption that the poster knows nothing. This may give the impression that you're being talked down to. The responder doesn't know exactly what you know, and rather than try to be a mind reader, gives you the whole story. I seem to have a "literary style" that some people have interpreted as hostile or harsh when in some cases the post wasn't intended to be. No, I'm not an angel and sometimes it is intentional. There are many of us who are rather abrupt, and possibly even rude. It's probably easier on your head to ignore some things, and just take away the knowledge and assistance offered. Separate the wheat from the chaff, as it were.
Keep in mind too, that a bad day on your part can heighten your sensitivity, thin out your skin, so to speak.
