I don't actually mind the name, when it's pronounced Dare-a. This is the way the only person I've met with the name pronounces it. She's American, a black woman in her forties, I think.
But I think pronunciation would be an issue if your friends want it pronounced Darr-a.
Before you criticize a man, walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes!
