I could care less

^^ I just really admired those 3 lines right there...that is a one big and sweet heart you have girl :) So sorry to hear about your friend, but you wrote a beautiful poem for him which should make him smile!
Loved it!

Sorry to hear about your friend Nik, hearing of something like this can really tear someone's heart apart, you feel helpless because something like cancer , there's just nothing you can do but to hope and pray thing will work out. A nice tribute and I'm sure he appreciates this very much.
