What fibro fog?  I left the house at 11 this morning.  I left work at 9.  I got downstairs and the doors were locked.  My boss was still upstairs.  So I went back up to tell her I was locked in.  She looked at me in disbelief and said, why didn’t you unlock them.  The thought never occurred to me.   And it took 5 minutes of hunting to figure out where and how the lock worked.

*sigh*
