This isn't la la land!

How do you deal with people who live in a dream land? I am a planner. I think everything out. People who don't do this drive me nuts! My problem is that I can't keep my mouth shut and let them continue to live in dream land. The thing that is even more frustrating is that when I try to burst their bubble they completely ignore the facts that I am giving them! When I hear their crazy plans that are never going to work I avoid the people because I don't want to go off on them. My hubby seems to not be bothered by the dream landers and I don't know how he does it. I was recently informed one of these never ending, never listening dream landers has made a decision that kind of affects my plan. Now I am left wondering if I should ignore their dream land plans and worry about my own realistic plan or if I should put off my own life so I keep the relationship closer. I emailed my wonderful friend T today about what is going on because she is not in dream land and gives great advice and is also kind of in a similar situation and she said I shouldn't let the dream landers slow my plan down. What do, you my wonderful frogs, think? Do you have people like this in your life? How do you deal with them?
