They are only as 'American' as you make them. I've been going to these nice tea parties here in UK for decades. Very pleasant occasions.
I agree. You pick and choose the good bits like happiness and anticipation, and leave out all the rubbishy stuff. A bonus is that you will also recognise the faces when the Christening comes round!
But Elless has made her decision, and that's absolutely fine. Good luck with the new grandchild and your developing role as a grandma. It's very much what you make it.
