No? Because I don't give a shit?

A name is just a label. A sound or set of symbols in an order that inspires the concept of that thing in someone else. In the case of someone's name, mispronouncing my name either has one of two consequences: 1. I don't hear it. My ear is keen on people saying my name (the way it's normally said), so if your pronunciation is too far off from how my name is normally said, my ear may not "hear" it, thinking you're taking to someone else and I will more or less ignore that you've "said my name".... OR, when you address me with the wrong pronunciation, I will recognise that the sounds you've chosen to use for me, while not typically the sounds associated with the concept of my self, are indeed referring to the same thing.

I comprehend what you mean, and that's the important bit. The letters/sounds used are secondary to the point effectively being understood.

I've been called by all kinds of names, plenty that sound like mine, there's a very common name that starts with a J that sounds like mine that I've gotten a lot, and I've even been called by completely different names, and I generally could not give less of a shit about it. Unless the speaker is a friend, or someone I care enough about to value their opinion, then why would I care?
