She wasn't "all that"

This week I went to a work related training, it was a long one 3 1/2 days. I pretty much figured out I didn't like the trainer from day 1. The problem is I can't stand people who think they know it all and this woman certainly did. She knew it all and she knew things she didn't even know she knew, according to her anyway.
As someone who trains folks,I've always looked at training as a give and take thing. Sure the person doing the training knows alot about the particular topic but that dosen't mean there isn't something they can learn along the way. I always learn something new at a training I give, sometimes it's topic reated, sometimes it's not and sometimes it's about what I can do better...that's OK with me. Obviously this woman was there to impart knowledge but her receive function was truly shut off. The best ( or worst) part is this woman was training people on how to mediate difficult situations with many parties involved. In my obviously wrong thinking what topic could lend itself more to a healthy give and take about what works, how styles differ and how personalities can effect the process.
Anyway I sat and basically listened to this woman read me her Powerpoint slides ( which I had a copy of in my training manual) for 3 days. I wasn't alone in my agony and many people at the training were reaching their maximum boredom level when she suggested a role play.
This would have been a fun and meaningful learing experience if she hadn't broken in in the middle of the "mediation" to correct the methods of a woman who's been doing this for over 16 years in a very rude and authoritarian way. For a moment I smelled revolt in the air but the assembled folk...all mediators for the most part took the high road and just told her they thought she'd been rude and she wasn't always right(many people told her this as politely as they could through clenched teeth).....this almost made sitting there for 3 days worth it.
So I guess the message is even the great ( in their own mind) can fall and it's up to us lesser mortals to determine how hard they land.
