For me
What as in like [name_f]Ferne[/name_f] Mccann?
I’m often asked if [name_f]Shelley[/name_f] is short for [name_f]Michelle[/name_f] (it isn’t) 
[name_m]Can[/name_m] I call you Em?
Is [name_f]Julie[/name_f] short for something / short for [name_f]Julia[/name_f]? No lol
“Did your parents like [name_f]Alice[/name_f] in Wonderland?” (no, it’s a family name)
“Is that with/without an h?”
“With a K?” “No” “Oh”
“Is it short for anything?”
When going by my nickname professionally, someone was wondering why I used the nickname.
