I'm having a day off...

Generally I'm a very chatty person. I love email, gabbing on the phone, sending texts, blogging whatever.
But occasionally, about once a month if truth be told, I retreat into myself and say nothing. I don't answer emails the way I should, I don't reply to texts and if you get me to answer the phone you are onto something.
And it's not that I don't care/ have something better to do / am an ignorant baggage - it's just that once a month I lose my belief in my ability to say anything at all worthwhile.
So I shut up.
Today I'm shutting up.
