lol. I'm surprised everyone seems so confused

I understand usually it just takes a few moments to realize your going the wrong way.. Just seeing if there was a trick to it..

I guess there are no tricks..
I was dealing with 2 - 2" brass unions the other day and they were unscrewed opposite from each other.. Meaning when they were installed one was reversed from the other. Breaking loose a 15 year old 2" union is hard enough with out having to go the wrong way and tighten it
