People who speak seemingly just to hear someone speak, why can't you ever just shut-up and enjoy the silence?
Simple answer: it's a psychological need. Why can't you just stop breathing? Physical need.
Your question carries a lot of bitterness and negativity. I would recommend talking to the one who you unjustly feel did you wrong and trying to understand why they have this need. Or, y'know, just learn to be polite and tolerate it while in their presence.
