Flowers fade, however and eventually die.
If you are like me, you take out the ones which begin to die off first so that you can maximise the beauty which remains in the bunch.
Sadly, the remaining flowers will have to be cast aside and binned as they too start to die off.
You do not leave the half dead flowers in the vase until they have all totally withered away!
Nor does the fact that you eventually throw them out mean that you have been in any way unappreciative of a fine gift. When you do dump them, this is not a metaphorical slap in the face to the giver.
Yet many Christians however, seem to use this very argument against voluntary euthanasia.
As a Christian, this issue troubles me deeply and I do not find the simplistic 'no, nay, never' of the Roman Church at all helpful.
