It rhymes with loony. I know.
My last name is Theune. I know it's confusing and Dutch, but it just sounds like "Toony." I know it confuses you that I prefer to go by my last name even though I happen to have an oddly spelled surname. It's really not that hard. I know it rhymes with loony, and I'm aware that it kind of sounds like the tuna fish. (You may not refer to me as Theune-fish.) Oh, and for the love of everything good and holy, I am already aware of how ironic it is that my father is a piano tuner.
It's not thee-une, thoone, toon, or thun.
My fucking name is Theune.
