Cartoon: Playing with Fire

This cartoon by Peter Brookes from The Times relates to the the tragic fire disaster in a London tower block, and illustrates a common English idiom: to play with fire.

London fire
The cartoon shows a number of tower blocks (or blocks of flats) as matchboxes. The message is clear — they are a great fire risk and a disaster waiting to happen. We won't know the cause of the London fire for a while, but it seems that residents' fears about the safety of the block were ignored. The expression 'to play with fire' means to take a risk or to do something that could cause you trouble later. • You're playing with fire if you try to cheat on the test.
