One of the things that stood out to me, (at least from the thoughts that ended up being provoked OUT of having read it,) was that in order for a friendship to be healthy & life-giving, both parties had to be 'givers' (my word;) nurturing, feeding, building up the relationship & the other person - a relationship where 1/both are 'takers' (again, my word) ends up with 1/both being taken advantage of, used & abused, all in the name of friendship.
It made me think about what I've tolerated (& also watched others tolerate) in the name of "keeping a friendship." Things like:
Maybe it's just that I have a different set of definitions when it comes to what a friend is & what a friend does & doesn't do. Maybe it's not being willing any longer to live with the sham of "as long as you're feeling ok & not offended today," relationships. Maybe it's being tired of carrying both sides of the relationship. Maybe it's the realization that there are many, many great people that hold a high value on true friendship that makes fakin' the funk not worth it, no matter how long standing the contact or how much water has gone under the bridge...
