¡Que se yo! (What do I know, a common saying in Argentina made with Italian type of hand gestures and shrugging of shoulders)

I've gone from preparing my house for lots of strangers to not having any strangers in my house-- or even friends. I got a label maker in case someone doesn't see where the minimum water line is on the electric tea kettle or cannot tell which is hand soap and which is dishwashing detergent. I basically tried to idiotproof my house and now I am the only idiot living here. I don't need the labels but I sure am using the fluffy new towels and I will use the new sheets...because who knows what the future holds? A pandemic encourages that attitude! "Who knows" is so frequently my answer to questions about my Big Trip.

We can't do WHAT? We can't go WHERE?

 I bought a unisex robe for guests and I bought a mattress cover, just in case someone has some kind of accident. I thought of many things though I refuse to get a carbon monoxide detector when there is no way I could have carbon monoxide in the house since everything is electric. 

Will I need any of this stuff, ever? I have a business license and a temporary housing license now. They last a year so it IS possible. Or maybe I won't rent my house out at all. Maybe I won't go or not for as long as two months.
