My partner bristles when anyone calls him by his full first name; he's 100% happy with the shortened version, which his dad also went by, and now hates to fly because the TSA demands ID with his full name (which, remarkably, he had managed to previously get with his shortened version). Interestingly, he doesn't mind so much when his full first name is used with his middle name, which is a last name that runs in his family.
I grew up being called by a common "short-for" version of my name by close family members. I detested it, and still do. Nobody who meets me makes the mistake of doing it more than once. Family members keep trying to find new short versions to call me (why??) and I've given up caring. My sister grew up with what I consider a very nice short-for name for her lovely -- but rare at the time -- full first name, then she went through a phase around 12 of very vocal resentment of the short-for and it disappeared. It wasn't a very obvious short-for anyway; just nice.
And my brother (straight, like sis) grew up with nothing but his full first name by all family members and friends, but as an adult mostly uses the short-for because that's what his college and adult friends just started calling him and he's cool with it.
