No, can't tell 100%, but I pay attention to what people say and consider myself a good judge of character. If a person says things that don't add up or contradict themselves, my opinion of them suffers. Don't sum everyone up quickly and I will view previous posts to see if responders are consistent in their logic.

And yes, use your head and think about what people tell you. When I was a kid my uncle used to hunt with an old fellow.. They were stump sitters...spent most of their time watching deer trails up in the mountains. The old guy would build a fire to keep warm, smoke cigarettes, etc. while he sat and he mentioned more than once that smoke didn't bother deer. My uncle didn't smoke and didn't build a fire.. Guess who killed the most deer on a regular basis? The old guy said my uncle was just plain lucky... Looking back, as a kid I believed the old guy... I didn't know any different and if he said smoke didn't bother deer, it must be true... He had hunted deer all of his life, so he should know. Now it's obvious that he was wrong... I can also remember him saying that he'd never shot a big buck and that he'd really like to. Hmmmmmm.......

Ha, I avoid the...
 

new expensive routes and ways of doing things.
Besides, I probably been doing it a cheaper way for years. Not going to change my way, just to spend more money.
