Chris describes OCD as a stray dog and you as a caring citizen. You're a good dude, and so you offee the poor dog some food. and that's nice of you. But what's the stray dog going to do when it's been offered a nice plate of food? Come back again? Move in? There are tough emotions felt perhaps in turning the helpless dog away. But the alternative is to ensure that s/he comes back again and again to exploit your kindness. Don't feed the dog.
