ELI5: Why does plucking nose hairs make you sneeze and/or cry?

Your nose is very sensitive and important. When you pluck a nose hair, your bodies defenses kick in. Your nervous system can't distinguish your actions to do what you want versus some critter or other irritant trying to gain access to your body. So, it starts up the two defense mechanisms: sneeze to force something out mechanically and tears to try to wash something out.
