To think that you believe there is only one use for a handkerchief is equally amusing.
Fair point. The problem is that it seems like it is a one use per wash kinda proposition. The most common being a big nose blow. I mean, if you blow your nose in the morning, you're not going to be straining water in the afternoon right or wiping your glasses. Seems like a flawed system.
Can always rinse the handkerchief out. Did that all the time when I was younger, working construction.
Slaves get what they need. Free men get what they want.
