"A Happy New Year!
Could you take refresh time with your family?
I could do with plenty Sake. I drank 3.6L per 2days. It was really enjoyment time for me!
Now it’s a time for working..."
That the English is not perfect is nothing special, you gotta respect that he, with limited abilities tried and the message came across. But what is noteworthy here is that he drank 3.6 liters over two days, and knowing the guy, this is the shouchuu type of liquor and not what goes for "sake" outside Japan. So the percentage of the stuff is between ~25% alcohol (normal "sake" would be ~13%).
He's a really nice guy and I could feel his happiness that he could have his "enjoyment time" with the booze while with his pretty large family (I have no information what the rest of the family thought of his enjoyment time), and I can also feel how hard it feels for him to be back at work...
