You just have to put a thick skin on at times. Some folks are prickly, that's just the way they are. Don't let it effect you. You are a bubbly character and are a credit to this forum and the trade we are in. Don't change because of other folks.
I'm the type who will always stop and chat with a fellow CC. Even if they are a local competitor.
I saw a CC a while ago working away in some empty student lets so I popped in to say hello. To say he wasn't pleased to see me would be an understatement. Maybe he was feeling defensive because he wasn't doing a very good job, who knows. But I will carry on because it can be lonely work at times and it's good to talk to others.
