The details nobody wants to know

I ducked into the hardware store at lunch to get a plunger, and when I started telling the sales assistant about my blocked shower, in the interests of friendly conversation while he took my money, he cut me off. He must be sick of hearing about blocked drains. And you, dear readers, probably wanted to cut me off also. But, I protest, it's the first blocked shower I have taken on all by myself, and you can be thankful that I didn't let you know about it when the toilet was blocked! (Which has been an ongoing problem since long before our time apparently and in the end involved realigning pipes somewhere.) I hate plumbing.
