Sometimes the most loving thing we can do is to say no. We are not meant to invite long-suffering and draw it to us in some kind of martyristic way. We are meant to recognize what and who is before us, and be respectful, certainly, and polite, but not blind. It is our responsibility to protect ourselves from those who would rob us of what we are willing to freely give.
I treat everyone with courtesy, but give the gifts of my spirit with care. I do not wear out my brightness on those who want to dull me down.
