A man has two girlfriends. Each lives at the opposite final stop of the same train. The man gets up every day at a random time. He goes to a train stop and takes the first train to come regardless of the direction and goes to the final stop to see the girlfriend which lives there. Surprisingly he sees one of the girlfriends 4 times more often than the other one. How can this be?


Hint

Think about train time intervals.
