I went to college far from home. My mom came out once during my sophomore year when I was very ill and hospitalized for a few days, and then for my graduation. Graduation was the only time my Dad stepped foot on campus. They only knew what I told them. My brother went to school more locally, and my parents watched his sports events, but in general, he shared even less information with them than I did. I can see parents really not knowing much about what is going on, or just feeling elated that their student has finally blossomed in college, and wanting to avoid bothering them so they can study and continue to win awards and accolades.
