Train to Dacha

Two schoolgirls were traveling from the city to a dacha (summer cottage) on an electric train.

“I notice,” one of the girls said, “that the dacha trains coming in the opposite direction pass us every 5 minutes. What do you think-how many dacha trains arrive in the city in an hour, given equal speeds in both directions?”

“Twelve, of course,” the other girl answered, “because 60 divided by 5 equals 12.”

Riddle Answer

Selfish Son

There was once a man who had a very selfish and unkind son. So one day the father sent his son to the market with one coin and said, “I am sick and tired of your selfish ways. Take this coin and buy with it: something to feed the cows, something to plant in the garden, something for us to eat, and something for us to drink. Don’t come back until you do this!” He is only allowed to buy one item.

What did he buy that fulfilled his father’s wish?
