I wish I had only a couple of names to juggle with. Unfortunately, it's custom & practice in our little niche to have a whole string of the dratted things which MUST include (or you will be hung, drawn and quartered) at least one Saint's name, a name commonly used in the far-flung different factions of the family, one (or more) of your own immediate familial names, a name of someone - somewhere - in the family who's been dead (usually for about a thousand years and no one can even remember them) plus one or two which your totally irrational parents deemed rather nice at the time of your birth.
Then everyone gets totally confused and starts calling you whatever they like the most, or whichever one they can remember, or what one comes from their branch of the family, or something entirely random because they seriously can't remember what your name actually is.
If I were brave, I'd drop the most of them and change by Deed Poll to Catriona Edwina - then I could be Cat here and Ted at home (which is fine as both of them are two of what I currently own).
Except for the grandkids, that'll have to remain as "Naaaaaaaaaan" - how can small children draw out a vowel to such ridiculous lengths when they want something ..... ?
I can't imagine being called lots of different names, although you must have always won the 'Letters in your name' jumping game (assuming you played it). I still have a scar from that game, courtesy of a brother who got annoyed when I jumped on the wrong letter when I was about four - my spelling and counting letters wasn't quite up to the required standard
My children could stretch "Muuuuuuuuuuuuuum" to annoying lengths. I always answered with "No" before they even asked for whatever it was they weren't going to get - evil Mother
