I'm not into it myself, but I know how much it means to my parents, particularly my father, who is a first generation American and so happy to have achieved what he has.
I realise it's our daughter's choice as a dual citizen where she wants to make her home, and that must be respected just as my parents respected my choice to make my life in the UK.
So this year we did a small BBQ and decorated the house, did a cake w/a sparkly candle, played some songs my sister sent over for our daughter's benefit, dressed Aillidh, our daughter, up in some duds my sis sent over from Old Navy and took photies for the family.
It's not my thing, but it means a lot to my family - and any excuse to eat cake makes Aillidh grin from ear to ear.
