Travails of an unique surname

D'Sa

That's my surname. Three major reactions are elicited to the first hearing.

1. It's D'Souza
Them: "Oh, you mean D'Souza."
Me: "No, if I meant D'Souza, I would have said D'Souza."
T: "So what is it then?"
Me: "D'Sa."
T: "Just D'Sa?"
Me: "What does that mean, just D'Sa? You want more?"
T: "No, no, why are you so testy?"
Me: "No reason."

2. It's an abbreviation
"So what does it stand for?"
My face morphs into a question mark
"Like, what is the full form, tell no."
"Full form of what?"
"Of D-S-A."
"It's a full name, nothing to expand."
"So how do I pronounce it?"
"Di-saa."
"Deee-saaa?"
"Close enough."
"And it's not an abbreviation?"
"No."

3. It's a spelling mistake
"Oh you mean, like D'Souza or D'Silva or something?"
"Yes, but only D'Sa."
"Why?"
"Why???"
"No so like what is the full-form?"
"That's it."
"And what does it stand for?"
"Diciest Surname of all."
"Ha ha ha."
"Exactly."

So, the next time you meet someone with my problems, remember - it's just D'Sa.
