I will go to read the vent because sometimes folks just need to air stuff out. I might have a solution to the problem. However, if it's a thread just to gripe about something, I go on to other things.
I'm not a Pollyanna, but I do try to look on the brighter side of things. I hope for the best & generally get it in some form. I just get a little frustrated when I'm trying to do that & folks just want to drag me down. But then again when that happens, I walk away from that person.
