"... en dank u nogmaals voor uw blijvende steun."

I'm not one to donate my hard-earned money on some humanitarian cause. Especially not to those boring folks who do nothing but pseudo pan-handling from door to door asking for money. They should be more creative, and then perhaps I would give it more thought.

However, one exception I take notice to is the NFGV which makes alot of sense.

The vital role that the 'geestelijke volksgezondheid' plays is not to be under estimated. Unfortunately, because there is often too little understanding and too much negativity in society, this gets pushed back in the closet, quickly forgotten and funds dry up.

Might as well help out with keeping a good thing going.
