Would you interfere with your neighbor’s quiet enjoyment on a summer evening?
Would you use a leaf blower to redistribute the leaves on your yard to your neighbor’s yard?
Would you let your children throw rocks at your neighbor’s windows?
Would you get on a crowded train with a high fever and projectile vomiting?
Would you show up at the office without bathing and brushing your teeth?
Would you ignore a fallen comrade on the battlefield?
If No to the above, why would you board an airplane plane without having the common decency to wear a mask, so that fellow passengers do not need to worry about you infecting them?
