Another observation to make is that there are only so few people in the fraternities or at a party at once and if you go every weekend all througout college you must remember every person at the party. This leads me to believe that everyone must know each other at this school or at least in the top tier fraternities everyone must be known by the top tier sororities who regularly attend their parties. And in the mid tier the mid tier must be known by all the mid tier. Sam with low tier. And even t the bars if you keep going to the same bar you must be seeng the same people.
