BB,
You think it’s funny that people, who you have no idea their medical situation , or their families or workplaces, are wearing n95 masks for protection?
Would you laugh when they die too? Or got deathly ill? Or even moderately? Or lose their sense of smell and taste?
Would you laugh at the yidden who still are severely restricted due to Covid?
Do not judge other people who are trying to protect themselves.
Maybe you should also wear one.
