You can save $10 just buy some hydrogen peroxide from the dollar store. Same thing.
I’m asthmatic. Flu is kryptonite for me. Unfortunately, once it’s in the air, there’s not a lot I can do to protect myself and my guests, other than those mentioned.
Your guest is probably feeling both sick and embarrassed. S/he may need bedding changeouts more often. Fruit juice and tea are always welcome. Offering to bring them some toast or something simple may help to cheer them. Suggesting a comedy seems to work wonders.
Thank you also for the reminder - as soon as the weather changes, we can expect the same here!
It turns out it wasn’t the flu, as he’d been given antibiotics by his doctor!
