Not all sunshine

It's not always sunshine and flatwater water here! Some days it's bleak and moody and atmospheric. And sometimes you're just tired. It's been a long feeling week or so and made even longer with some day off shuffling to cover sickness. Today's group had lots of fun and were safe so know no difference but I know they didn't get my best and that never sits well with me. 
A proper day off tomorrow to decompress and repack the brain boxes!
