Do Know It Alls Really Know It All?

Admit it, everyone knows a "know it all". They are the ones that are doctors, nurses, teachers, poets, motivational coaches, personal trainers, and any other profession this world holds. No matter if you are 100% positive you have the correct information with proof to back it, they are always going to try and convince you that you are wrong. They can't ever let you just say "this day sucks". They have to reply with something to the effect of "this day is beautiful and what you make of it". Well, maybe events have happened to make the day suck. Why can't my day suck? I often want to ask them how many years of medical training they had to tell everyone proper diagnosis' and treatments. Maybe I'm just getting old and cranky and starting to notice it. Maybe one day I'll stop trying to be nice and actually challenge them. Who knows maybe one I'll try to be the know it all. Wonder how many people would still want to be around me if I was. I'm pretty sure not to many. I think one day the know it alls will wake up and realize their group of friends have decreased. But of course since they do know it all, it won't be their fault. Ok, I feel better now.
