Everyone in my family just turns their head to the side and lets their sneeze rip into the house. I've only convinced one of them to cover their sneeze sometimes.
I told my sister that if she couldn't grab a tissue in time, then she could pull the collar of her T-shirt up over her nose (a move I copied from my friend from Vietnam) and she said "that's gross!" 
...But coating the entire room in a fine mist of the same stuff isn't!? That's like opting to throw your turd at a moving house fan instead of shitting your pants.
I also had a classmate who would sneeze with so much substance that I could literally see chunks of snot hit the floor. 
I remember when I tried to explain to my angry, half-witted brother that masks during covid were never meant to protect you but the people around you, and said "It's sort of like covering your mouth when you sneeze except full-time," and he just looked at me like I was speaking a foreign language.
