bring back memories

In psychology class Tuesday, I being the oldest student in the class was asked to participate in a test.  The test was to try and answer as many questions as possible that the teacher asked me about my first day in kindergarden.  Since it has been 24 yrs since that day I remember very little.  After taking the test I knew very little.  The teacher informed me that because she had brought up many thoughts about something I havn't thought about in years that it would re-spike my interest, and when a come back to class on Thursday I would remember most of the questions she asked me.  Trying to be a good, participating student, I even tried thinking about my first day in kindergarden just befor I went to bed so I would perhapes unconsciously think about it.  Unfortunatlly as of right know I don't remember any addition things from that time.  I think it is because I have so much more important things on my mind, that my mind never had the oppertunity to bring up meaningless thoughts from so long ago.
