Relationships die without context.
Take a strong friendship that "works" while two people are both part of the same context, and see what happens if that context is removed prematurely. Contexts can include clubs, sports teams, work, neighborhoods, churches, and more. Relationships developed any of these contexts can be real and substantial, yet if the context is removed (Ex. the church dissolves) then the relationships will langure in emotional purgatory for a while and eventually feel like a flat as a two liter of Mountain Dew.
Its not the friendship cannot rediscover itself in a new context, they just don't most of the time.
Context is what keeps it from provides the place to see each other and remember how much you appreciate each other.
Context is what provides the rhythm of the relationship.
Context is the fabric upon which the friendship is written.
Not all contexts are equal, and not all are easily replaced.
