So, SIL and I are from completely different planets, culturally speaking. She's always doing something that I find incredibly rude, or odd, or whatever, and I try to just shrug it off. The few things I've asked about on the Dis, I've been informed that her behavior is perfectly normal for her religious culture and the area she grew up, etc. (She's from the 5 Towns area of Long Island, I'm, well, Southern....) I'm sure I'm her "difficult person" as well - we just do not live in the same world.
So, in the interest of not leaping to wrong conclusions, I'm sharing yesterday's text exchange for your review and impressions.
Background: she and my brother have a 17 month old daughter. I'd love to be spoiling my niece rotten, but they are pretty picky about gifts and clothing for her, and basically have trained me not to get her anything without detailed direction from them. (and that's a whole 'nother post

)
So, I'm in Target yesterday, and on the endcap of the kiddie shoe aisle, there is displayed an adorable little pair of pink suede boots with fringe - the kind of thing my DD would have loved at that age. I snapped a picture of them, and texted SIL:
Me: OMG, sooooo cute! Would niece like these?
Her: Yes, she would, super cute.
Me: Size?
Her: 7 in US sizes, 23 in European.
Soooo,

what the heck? Is this standard NYC speak for sharing your child's sizes? Is the city so multi-cultural that one could very easily be buying European stuff? I'm in Target, for crying out loud.
Even if one is routinely shelling out for pricey European shoes for a 17 month old, is that something that really needs to be broadcast? Wouldn't it be enough to give the US size, and if I happened to be in a posh boutique offering to buy DN a pair of designer boots, then I could text back, "no dahling, I need the UK size"?
Your thoughts? Is she a pretentious snob, or am I a clueless country gal? Or is she a clueless spoiled city girl? Or, is this yet again an example of we will never "get" each other?
