Sometimes I call it a bout of unbelieveable laziness and a squandering of time much better spent creating and/or doing.
Sometimes I call it a body's perfectly normal and natural need to have a little down time.
Sometimes I think it's a result of a very busy work schedule complicated by things like back pain and a need to get everything done as quickly as possible.
Sometimes I think it's a result of an unwillingness and/or motivation to move ones a$$ off the couch.
Whatever it is, whatever its cause, I got it. I told Hubby that for the first time in a few years, I wish we had a TV in the bedroom. But we don't. And since I've spent the first large chunk of the evening laying on the couch in front of the TV, it's time to spend the next large chunk of the evening in bed, reading.
And sometimes? Sometimes I just call it Friday night.
