Tapping on your brain

Ever have the feeling that something is tapping on your brain?    Well, the roofers are still not done.  They have extended the time alloted to one and a half more days.      Mainly because we have solar panels on the upper lever (that's over my head).   When you put a new roof down, they have to be moved and then moved again and a couple more times.    So, not only do I hear the tapping and hammering, I hear the scraping and dragging sounds.    I'm getting quite tired of it, but will be very relieved to have it done and enjoy the security of a good sound roof with a long warranty.     Here comes the truck again with another load of stuff.
