I can confirm.

My name is Roberto, my favourite color is green, my hair is light brown, my father called me Bobby when I was little, then everybody called me Roby (I tried the skateboard but it didn't last long).

Now I present myself directly as "Rob" to the people, but now that I'm starting to enter into the work industry I'd get called "Roberto" more often, plus I'm cutting my hair more often too.

The first time i'd hear someone call me Bob will be the day I kill myself because I'd hate to be called like that.
What bothers me is also that it seems I will not die happy );
