After having to rush back home to fetch a second umbrella because the first one refused to stay taut, I arrived at the life session and put the new umbrella in my bag.
I've no idea what happened to it while it was in there but when I came to use it on the way home it refused to stay up and repeatedly collapsed onto my head like a venus flytrap. I had to hold it open with 2 hands which is no mean feat carrying 2 bags as well. In fact it was in such a state there was a great big hole near the centre letting the rain in anyway!
It's now in the bin.
