I've seen this issue on here several times, and have experienced it several more times personally. I feel that is someone wants me to leave them alone, they should say it.
That said, when an annoying or stupid person is contacting me in an irritating fashion, I now tend to let them spin until I am good and ready. Otherwise, they will never leave me alone. The only way to deal with some people is avoidance. Perhaps we are misclassified as such?
Keep in mind, Robison mentioned this in his latest book - that not all relationships are equal. Some people you will be in constant contact with, and others will check in on you every few months, or during holidays. Apparently that's just how it works.
