The explanation

A typical conversation between Ms. Standoffish (Ms. S) and the would-be-could-be-but-ain't potential life partner (WBCBBAPLP).

WBCBBAPLP: Why are you so quiet? (With pretentious charming inquisitive look)
Ms. Standoffish: No reason. (Smirks and the pretends not to notice pretentious charming inquisitive look)

WBCBBAPLP: What are you thinking about? (Pretends to smirk, but curiousity bites his tounge)
Ms. S: Nothing. (Smirks again- she is the Goddess of Smirking)

WBCBBAPLP turns to Ms. S's friend.

WBCBBAPLP: Why is she still single?
Ms. S's friend: Coz she's picky. (Smirks to hide the truth)

WBCBBAPLP turns to Ms. S.

WBCBBAPLP: Why are you picky? (Squints as if he knows the answer)
Ms. S: I don't know. (Turns away- she knows this line of questioning already)

WBCBBAPLP: You're standoffish, you know? Has anyone told you that?
Ms. S: Yeah. (Thinks to herself: damn it. You're the nth person who's told me this.)

WBCBBAPLP: You're intimidating; though, I'm not intimidated.
Ms. S: (Thinks to her self: like that line is gonna get you anywhere but closer to the door. Smiles and nods at WBCBBAPLP.)

Ms. S starts to think about what she could have done if she stayed at home instead.

Not a good sign.
