Waiting game

I spent the majority of today like I've spent the majority of my week, sitting in the doctor's office. Just the same as every time, I waited in the waiting room for a few hours, then waited in the examining room for a few hours. But today was even worse. The doctor came in after the nurse did her thing and when the doctor was on her way out she said something that sounded like, "The nurse will come back."
But then no one came back. I waited a long time. I looked through all drawers and cabinets, built somethings out of popsicle sticks and tried on a dozen pair of gloves. But no one came back. So, after a good thirty minutes, I left. I just kind of walked out without making eye contact. No one stopped me. 
I'm just not very good at being patience. I can stand in lines for any theme park ride or movie premiere. But I can't stand waiting when there isn't a worthy end. For example: waiting to have a third nurse check me out is not worth my time. Just like waiting to find out a surprise is not worth it. Moral:  my third biggest pet peeve is when someone says, "I got you something but I'm not going to give it to you until later" oh, and I should probably not be alone in a hospital room.
