My dd1 has always done it with friends.
My maternal GM was Phoebe (which she hated). My DF always called her Phoeb, which she was happy with, but then she adored my father.
But it resulted in my brother when still quite small, beginning a thank-you letter with, ‘Dear Feeb,’
It was posted off uncorrected - I dare say she enjoyed it all the more.
Girls grammars in the 60s (and beyond)
Favourite small treat when feeling blue or conversely a bit flush
