Has anyone ever experienced the act of saying something (a phrase or comment) that is totally uncharacteristic of you? 
For example, the other night my husband asked me if I would like some pie.  I was watching TV and not really paying attention to him or the tele.  Almost in a trance like state.  And I heard myself say, "I don't care for any thank you."  You might ask, what was wrong with that?  But I am not usually that formal with my husband and I don't think those words have ever crossed my lips before.  What I would normally say is Nope.  Or No Thanks.
It felt strange to me to say that, and yet it flowed out so easily as if I have always said it.  And it didn't even feel like I had said it.  Strange and wacky.
