Reasons why people think I'm a total sucker

I'm a total sucker at socializing, especially with strangers. This is what usually happens:

Postman: Is Ms Cori here?

Me: *stares like an idiot*

P: Is Ms Cori here?

M: Ms-- Oh no, she's off to work.

P: Oh, right. Nobody's at home?

M: Uhhh... Yeah...

P: Fine. Sign this paper here and I'll be off.

M: I'm not Ms Cori...

P: *getting impatient* I know, just sign it.

M: But I'm not Ms Cori...

P: *exasperated* I know, it's okay if you're not Ms Cori, I just need someone to sign this paper!

M: Oh, sure, yeah. *fumbles with pen* There.

P: Thank you. Bye.

Smooth move, Vi. Smooth going.
Another scenario which just happened today which by the way, is in a foreign country:

(hotel doorbell sounds)
(I open it)

Lady: Hi! Is this Ms Cori's room? May I enter?

Me: *slow brain trying to process information* Uhhh...

Lady: *thinks I don't speak English* @&%@&% (speaks the country's language)

Me: *stares some more*

Lady: *getting exasperated* @&%@&%!

Me: Uhhh... Sorry I don't speak your language.

Lady: Okay, fine. Is this Ms Cori's room?

Me: *nods*

Lady: Can I enter? I have to serve her the supplements.

Me: *nods* *opens the door wider*

Wow. I'm certainly wonderful at that. *excessive head-desking*

So that's me. The wunnerful Violette of ummm... Slow brain syndrome strikes again. The joy.
