Based on the context and the answer, generate a question. 

Context: Classy ! I believe wondering when your good deed is going to pay off is pretty much the opposite of doing a good deed . Anyway , despite that ridiculous thought , there have been plenty of times that some complete stranger did something nice for me -- many more times than I ' ve done the same in return . After college , in Cambridge , Massachusetts , I had just finished the Radcliffe Publishing Course and was hauling my suitcase to the T station to get to the airport . That shit was heavy .

Answer:
