Once, two ants were talking....

.....Now there's a novelty.  Anyway,  'Try this,' said the first. 'It is a white crystal with an amazing taste. Humans call it sugar.' 'That's interesting,' said the second ant. 'I've got a white crystal of my own called salt.' 

They decided to swap, but each was worried that he might lose his favourite flavour. So the first ant sneakily took a big mouthful of sugar first. While the second did the same with the salt. Then each said the same. 'There's no difference.' 

So often we run the risk of failing to give something or someone a fair trial.

If there is no struggle, there is no progress.   (Frederick Douglass)
