For some reason I do not like talking about money. I don't like to tell anyone how much me and dh earn, even my dc. Teenage ds has asked a few times what we earn and I just say it's for me to know. I'm not keen on being asked how much I've paid for things either.
I just feel that it's private but also that it's a bit vulgar.
Dhs parents are always telling us the ins and outs of sil finances (husbands sister). How much they earn, details of what their savings and outgoings are, every detail. I am surprised that not only they know so much but that they keep relating it back to us.
