I'll be brief... It's absolutely impossible to feel ladylike while doing the following:
a) Blowing one's nose (even with a silk handkerchief)
b) Gargling with salt water (even from a crystal goblet)
c) Coughing up one's lung (even though TB has been made to seem romantic)
d) "Sweating out" a fever (even if reclining on a fancy chaise lounge)
All of the above is just, straight up, gross.
