Two different incidents..

A surprise bridal shower-
Me: Congratulations!
The bride-to-be(BTB): thanks..I wonder who leaked the information..
Me: Was it supposed to be a secret?
BTB: Yes
Me: I hope this was a pleasant surprise
silence..
BTB, I totally get you. Why does everybody think that everybody likes the whole world to know they are getting married and want to share their joy with the very same whole world?

Three of us climbing up the steps - me, BL, neighbor-next-door(NND); NND is a totally unknown figure to both BL and me, though we have been neighbors’ for some time.
Me: Do you have kids?
NND: Yeah, a daughter of 3. What about you?
Me: A son of 13 months.
I don't know how this happened but in a span of 2 minutes BL ferrets out the information that NND's parents are here visiting her and that her husband does not stay with her and this is when I tune back in again.

BL: So, where does your husband stay?
NND: In China
BL: When will he get back?
NND: No, he stays there and I stay here.
BL: Is he planning to come here?
NND: No, his English is quite poor and I don't think he can survive here.
BL: So, what are your long term plans?
we are at our place and NND shrugs and walks away.
1)BL is like that only. She will ask the most intimate details and I'll be the embarrassed one.
2) The entire afternoon I kept thinking about it. I am a single mom during the weekdays and I am already tired of analyzing 'is this what I want from life' kind of questions. What is the motivating factor in NND's life? I mean, I can understand that she is making good money but at the cost of what? I.just.don't.get.it!! I am truly baffled and I want to cry when I think of her daugheter. And her husband.
