Some things I cannot change

I'm sure it won't come as a surprise to anyone here that I am not really "down with the kids" in terms of things that are trendy or fashionable. My cousin's 21st birthday is coming up in mid March, and, considering that: a). it's her 21st, b). there was a point when we weren't sure she'd live to see it, and c). she's really spoilt anyway, she's asked us to get her some Tiffany jewellery.

Maybe it's because of my aforementioned lack of downness re: the kids, but to me this just looks like something a chav would get from Argos for his girlfriend for their 1 week anniversary. It's not even proper silver, it's sterling silver, but because it's made by Tiffany (via Elizabeth Duke) it costs £220! Here is an Argos one that looks, to me at least, pretty much that same, but costs £30.

Here's another thing she wants: a charm to go on the bracklet. It's .. it's a little sterling silver cube padlock. That costs £90! Seriously.

Am I just being old and curmudgeonly? Am I not properly appreciating the value of the craftsmanship of the small slave-labour children working in the Tiffany factories in south-east Asia?

I just don't understand it.
