Simply stated? It is mostly our Black & White attitude!

Too simplistic an explanation? Watch, if you can, your feelings about a certain issue, position you have taken, etc., and see how extreme they are from one time of consideration to the next.

This can be really hard for anyone to keep up with! (But I think it's because we can project too many scenarios as we gain more insight!) Just my opinion, though.

Oh, and of course, this is only ONE aspect of why people have difficulties dealing with us.
