Then I know how I well spend eternity.
It will be on a return journey from work on the underground with an apprentice that is attempting to do the Evening Standard easy crossword.
First of all he starts off by writing a few answers that he knows and then it goes downhill and he starts adding words that fit the squares but only have a small semblance to the real answer eg 3 Reptile 3 letters and he knows it begins with A so he puts in ANT.
When he runs out of words he knows that will fit he then starts to make up words or he just misses letters out of words or adds letters to words to make them fit.
After that the nightmare begins and goes like this
"Adam?" "Yes" "What's another word for "insert crossword clue here"?"
Repeat for every clue he has not filled in.
The final torment is when we get off the train he bins the paper (ie leaves it on the train seat) and says "One of these days I will finish that crossword".
