A cousin of mine is fond of collecting toy trains. If he knows a friend of a relative that is traveling abroad, he will immediately ask that person to buy him toy train. This would mean that he would give them his money so that the person who is going to buy will be more obligated to fulfill his or her request to him. It is almost twenty years and he has not let go of this hobby. He has been asking me to buy him toy trains, but I never had the time to do so. It will be his birthday next month and the closest thing I can give him are train sterling silver cufflinks.
