[Opinions] Re: Nickname or full name?
I prefer giving them a full name and calling them by the nn.
I undertsand your point, but just because you are calling Caroline Carrie when she is little, doesn't mean it's always going to be that way. If she has Caroline to fall back on, she can go by it when she's older if she wants to.
I, personally, also like the idea of having a longer name to put on certificates and job applications. I just think it allows differing degrees of familiarity in relationships as well.
Also - when they're in trouble you get to call them by their full name. :D
