A paper bag with a slogan is still a good method. Technically it's a mask so any Gestapo can fuck off but at the same time it ridicules the current situation very well. Never underestimate the power of humour, even in a tragic situation.
Sorry man, but here in this shit-hole you now need to wear a MEDICAL mask ANYTIME when you have a VALID REASON to leave your home. 110% compliance, it disgusts me, makes me want to do things I've never imagined before.
We are such a small group it's not even funny and these echo chambers are not helping us, even though we need them to stay sane.
