My simple answeris that friendships endbecause the situationsfriends are in or even the friendsthemselves change. Others havesimilar answers. First, thesituations friends face may change. The decision to relocatefor a new school or job cannot help butaffect a friendship. Likewise, if a friend is in an accident, develops an illness, or loses someoneclose, these situationscannot help but affect a friendship. Does a friendship need to end because ofthese changes? No, but it’ll require adjustments that one or both friends might not bewilling to make.
