Handkerchiefs - now that could be a whole big topic. I used to incorporate them into my life - I didn't see anything weird about it - but some girlfriend at some point was suddenly like, "You use a handkerchief wtf?"
And I was like, "Well what the fuck, wtf?"
But I am very insecure about my grasp on social norms and I recall that someone else corroborated the idea that I was being gross by using hankies so I phased out handkerchiefs and I no longer have any. It has not been long however. Maybe a couple years since the last threadbare hankie was disposed of.
But I really don't know what the fuck.
