Being a third culture kid living in a second foreign country like me is very different in many instances. Father's Day, as well as Mother's Day, is one good example.
I was born in Brazil (as were my parents), and there we celebrate Father's day in August. Nevertheless, I was raised in Portugal, and my parents still live there, where they celebrate Father's Day in March.
I live in California now. Father's Day was yesterday here in the US. It's funny that most people I know ask me kind of in a pitiful way "What are your plans for Father's Day?" because I don't have parents to spend these days with...
I used to care.
I actually used to care and be upset about it... nowadays I look at the glass half full. I get to "celebrate" Father's Day 3 times in a year. Mother's Day twice (it's the same here and in Brazil). And I guess the parents also like the extra attention. And when I'm here, I get to hang out with people who are taking good care of me while I'm here. So there's no reason to feel pity for me.
By the way, that's my Dad in the picture, Mr. Kawauchi, standing next to Mr. Koizumi, Japan's ex Prime Minister. My Dad was Mr. Koizumi's interpreter in his last visit to Portugal. Yes, it's good to have a Father to look up to :)
