To ask how sister-in-law got her money

[SweetSouberry]

It would be really rude to ask wouldn’t it but I am fascinated?

how is it your business?

It would be very rude to ask, and if I were her, I would be extremely put off if you did. Absolutely none of your business.

Well yes probably, unless you’re close! Could you find out another way? Does she have a job?

In what context though?

Has she suddenly come in to some dosh and you’re being nosey or are you wondering how she’s built herself a decent life because of work and want to know how she did it?

So she must be rich.

Of course it's rude.

It would be okay to ask her about her job. But, "where she got her money," implies that you think it was something kind of shady, and yes it would be rude to ask her about that.

Under what context?

I’m guessing inheritance or maybe she just has a job that’s much higher paying than you imagine or she’s got a bonus

Lottery
Inheritance
Cummings relative

Alternatively:
Drugs
Smuggling

However, I think you may need to ask her, unless you want to engage a private detective’s services. I am lacking the ability of mind reading from this distance 😂

MYOB.

Why don’t you just ask your husband? Are they estranged?

I think it depends on context, to say 'you're so successful, your business is thriving, you're a single parent to three child geniuses, your home is immaculate and you provide a very nice lifestyle for your family how do you do it?' or even 'you've made such a good shot of your career/business I'm struggling a bit do you have any advice' Is very different to 'and how are you so well off?!?!'

My mouth actually dropped open at this question however as I may be the SIL - if I am, the answers won't surprise you!
a) It is none of your business.
b) Because of how you alienated us you'll never know.
c) No, we haven't left anything to your children because of b
d) If you hadn't been such a controlling shit SIL you'd be benefitting already.

Blimey!

Totally totally none of my business and I am really nosey, not going to lie. She is going to marry my husband’s brother.

She has a job in that she works for herself.

Well how much do you think she has?

Are you sure she has got lots of money? If your only evidence is what she posts on SM then it might all be bullshit

Well, she's either successful and makes her own or she has indulgent rich parents and regular handouts.

Your DH could simply ask his brother.

She has a job in that she works for herself

Is she a successful businesswoman?

Well your husbands brother will know. Surely she works/they’d have wanted you to know if it was a lottery win.
@TARSCOUT I don’t know why but I really like your post!

I would say more info needed, but there actually isn't. Mind your own business.

Your DH could simply ask his brother.

This isn't any of her husband's business either.

I totally get your curiosity but in a million years would never ask. I live in quite a wealthy area and some friends do seem to have loads of money ( based on lifestyle and property) I know the salaries of some (ish) based on their public sector scales and of course I'm curious! How DID you buy this house? type thing. Inheritance? Lottery win? Gifted? Side hustle? Or did you simply not spend from birth and save every dubloon? Its perfectly natural to wonder but v rude to ask

There's probably a way you can find out without asking her directly.
