I sometimes wonder if annoying people are sent to us so that we can address the annoying aspects of our own personalities.
My ego says, and no doubt yours does too, that annoying people really are just that.
They talk too much about themselves, or about topics you have no interest in, or just talk too much.
They might be neighbours who are overly neighbourly or nosey.
They might be acquaintances who think the world is going to hell in a hand basket and see evidence of that point of view everywhere.
Maybe annoying people just need our compassion. Or more so, maybe they just need a friend who will listen.
