Visiting Nana is always interesting – except for last weekend. She was busy mending some rather large item of clothing, and she said to me "Now then, you choose: You can do the washing up (there was quite a lot), OR you can go into my black elastic drawer - and fetch me the second largest loop of elastic there is! I know it's a bit of a tangle, but I'm sure a bright young mind like you can find it with no difficulty.
Fool that I am I chose the elastic. What a tedious chore! Next time I will volunteer to do the washing up instead.
