[Opinions] Re: Nicknames and full names
I voted full name because only a few people shorten my name and I rarely introduce myself to others with a nickname.
In my family it varies. My grandad was ALWAYS Alf, never Alfred. My other grandpa is often Ken, not Kenneth and at my granny's funeral I noticed everyone referred to her as Phyl, not Phyllis. My mum never shortens her name now but did sometimes when she was younger. My cousin mostly goes by her full name. My brother tends to get his name shortened but then Christopher is quite long. I use both to refer to him and I notice on FB he uses Christopher and not Chris.
With friends and colleagues I'd say most friends with longer names seem to shorten them (Jess, Steph, Alex, Ben, Allie, Will, Nette, Pete) etc.
So, after much rambling, I'd say nicknames are more common.
