Hi Ping
I am a little late, sorry
I have been to much ocupied at COP15 in Copenhagen .
But here it comes: congratulations on the birthday(s all of you) and nice tattoo you have got.
I got my first tattoo in OZ together with my ex. I turned 30, we got engaged and wanted something else than rings. She got it on her hip, I got the same on my shoulder. It was the Chinese symbol for you-are-special (or so the lady told us.. maybe it stands for sour-sweet-souce or eat-here-or-take-home.... My Chinese is still not good enough)
A few years later I got another tattoo from the same lady. Now having two on the left shoulder.
But probably not something my mom is proud of, though her dad was a man of the sea...
Anyway. Late congratulations from me, and have a ball of a time towards the next 
BR
