I have always been a frequent sneezer and nose-blower (until I finally got the better of my allergies). I stopped using tissue when I realized how much it (a) costs me money, (b) uses up virgin forests and produces vile chemicals in its manufacture, and © (worst) rubs my poor nose all raw and makes it hurt for days after the sneezing ends.
So I use fabric: old T-shirts when I’m at home, handkerchiefs when I’m out. I don’t buy kleenex at all; I hope my guests would respect that (seeing as I produce far more snot than any of them, I think they usually do.)
If I’m in someone’s house and I didn’t come prepared, I will happily use their toilet paper. But I do my very best to come prepared. I once cleaned out an entire cottage of paper products (kleenex, TP, paper towels, napkins) because I hadn’t come prepared; I was so embarassed I re-evaluated my entire nose-blowing strategy.
I don’t mind TP over Kleenex in someone else’s house because it’s much more discreet. Imagine you are in your guests’ living room and you get the urge. Normally I excuse myself to sneeze/blow my nose anyway (if I get enough warning, which I usually do). I don’t like to hear anybody’s bodily fluids (particularly in polite company) and I don’t want to subject anyone to hearing mine. So since I’m leaving the room anyway I might as well go to the bathroom.
Also, now, imagine if you don’t leave the room, you just grab a tissue and blow away. Now, what do you do with your snotty kleenex? You have to either try to keep a tidy, discreet pile of nasty kleenex somewhere near you (or shove it in your pocket or up your sleeve); hope there’s a garbage bin within reach; or leave the room to throw it out. The only thing I want to do with snotty tissues is get them away from me as quickly as possible, so I can’t imagine option 1; if option 2 is out, only option 3 is left - and again, since you’re leaving the room anyway, might as well head to the can.
Nope, fabric. And, in the spirit of gigi’s post above - when there aren’t any clean ones, I use ::hangs head in shame:: my cleanest washcloths.
My guests aren’t expecting formality when they come to my place. Thank goodness.
