My first job in London was working with a load of Sloane Rangers, and nearly all of them kept their childhood nick names.
As someone whose parents refused to give their children middle names, because they thought it pretentious, it took quite a while for me to comfortably call twenty odd year olds Ploppy (Peregrine's Nanny's toilet training name), Nu-Nu (Miranda, the 'newest' child), Ade (Lady Victoria, appeared late in Burke's Peerage as ada, a daughter also.)
Glad this isn't just confined to the nobs.
