I was thoroughly entertained for a couple of weeks by watching a new roof being put on the gazebo across the street. They were putting on wooden shingles, that's what had been on it before. And yes, you could see there feet slipping at times as they walked across it. Mostly they were careful.
What I was really looking forward to was watching them put the tin and wooden topper back on.
Then I got distracted for 15 minutes. Next time I looked the topper was on and the guys were packing up to leave.
