In New Zealand, where they still say fortnight, the birthday boy or girl gets two weeks of celebration. At least according to Meredith; I haven't confirmed this with Flight of the Conchords yet. Saturday she wanted to dance, so we all went to Seoul to dance the night away. For the evening I bought a special cardigan. See below.
My stated goal by the end the year is to be dressing like the coolest 15 year old Korean boy on the peninsula. So far so good.
