Never Speak! No Never!
Introverts don’t hide in their homes indefinitely throughout the recharging period. There are times when they’re forced to go outside and soak in some vitamin D. Those times are usually when their Amazon Prime purchase arrives at their doorstep. If you live next to an introvert, try not to look at them for too long.
The paleness of their skin from a lack of natural light will blind you like a solar eclipse. Just avert your eyes, try to ignore the smell of someone not taking a shower for weeks on end, and go about your business like usual.
