Very old anecdote, so old I can’t even remember when it happened. Definitely pre-2005 though since that is when “Barbie” abandoned me in order to study abroad.
“Barbie” and I were working in a staff area of the library when “Ralph” came over. I don’t know how we got on the subject, but suddenly Ralph got very serious.
Ralph: “I have a question I need to ask you.”
Miss Print: “Okay.”
Ralph: “What does BFF mean?”
Barbie/Miss Print: *laughs*
Ralph: “I hope it’s not something dirty.”
We went on to inform him that BFF is, in fact, appropriate for all ages being an acronym of Best Friends Forever.
