When I watch the line-up for outside the grocery store, I just shut-the-fuck-up and join the line and try not to hack and cough or to touch anyone, to stay 10 meters distance..... This has happened before. That does not make me feel good [Nya nyah not me! or bullshit like that. We are all in this together, take care or yourself and others too], not at all. TRY TO NOT TOUCH OTHER PEOPLE. SMILE AND NOD. WASH THOSE HANDS, AS MANY TIME AS YOU ARE ABLE TO. DON'T MOUTH-BREATH STAY AT HOME AS MUCH AS YOU ARE ABLE TO. HANGING GARLIC AT THE DOOR PROBABLY WON'T HELP, AND THE AROMA MAKES PEOPLE GO MAD, IF THEY HAVE NOT EATEN FOR A WHILE or even if they have!!
