what to write?

ever have a day where you have so much to say but don't really know how to say it?
or are in a conversation with someone and you really want to say SHUT UP and just listen for a change?
why are conversations so hard to have?
really they are only words, how hard can it be?
of course life gets in the way, we ourselves get in our own way and tend to suffer the classic case of foot in mouth disease, disastrous!
