"Excuse me, is this the road to Suwalki?" the tourist asks.
"Yes, it is," says the farmer.
"How far is it?"
"Half an hour by cart."
"May I ride with you?"
"Certainly."
After half an hour, the tourist begins to grow uneasy.
"How much further is it to Suwalki by cart?" he queries.
"Oh, an hour or so."
"What? You told me it was only half an hour away, and we have been travelling that long already!"
