A young chap on a walking holiday in Ireland was out on a wild country road when it began to look like rain. He wondered if he should go on, or go back?

Fortunately he came across old Tommy digging peat and asked him how long it would take to get to the next village.

Old Tommy didn't speak or even look at the chap, so, reshouldering his knapsack, he went on his way.

He had only gone a few yards further along the road when old Tommy hailed him to come back.

"It will take you twenty minutes" he said, with a nod.

"Thanks, but why did you not tell me that before?" asked the chap.

"Because then" Tommy replied, "I didn't know how fast you could walk"
