It's totally wrecked :( !
For ages I couldn't bring myself to look to see what damage was done. When I finally did, things were just as bad as I feared - pretty well all of the glazing bars on the sides are broken in at least one place and pieces are missing in lots of places. It didn't even occur to me to check the soles of Peter's sneakers before he left the house for little pieces - I was too shocked. And it's been raining for several days so any little bits that were caught in the tread of his shoes has probably been trodden into the mud.
I have scoured the carpet thoroughly and can't even find all the pieces to fill in the breaks, . I have found the little decorative bit that was broken off the top but there are still lots of pieces gone from the sides. The bench supports are broken off and in several pieces, and the roof has gaps in it everywhere. I rang Peter and asked him to check his shoes but I think it's too late. And I think the damage is too extensive anyway so at the moment I can't think want to do. I am so upset and sad.
