How Reliablle is Our Memory for Our Own Previous Intentions

I think that when they were asked later they felt uninclined to answer the question correctly.  when people just bought the CD i think that they were probably just more excited and eager to answer the wuestions.  I think that when the questions they asked weren't revelant to what was goingon in thir life at that time they were less interested and didn't try to recall the day they bought the cd.  I also think it was dumb someone tried to sue eminem because people listen to eminem more than him, and probably didn't even notice their songs were similar
