nowaday it's SEASON of "a year-end party"
It says "held to help people forget the troubles of the past year" in a dictionary.
It's not a party really for foregetting the troubles. Just in name only.
It's simply "Go Drinking".

so I've had it with ex-colleagues a week ago
I attended at the meeting with a current company's colleagues a week ago
and with a current developtmenet team today!

we'll have a great course dinner in a restaurant.
and will talk about any topics as usual.
Normaly it's not all, after finish the dinner, people go somewhere else and continue the party - another bar or Karaoke etc.

Oh Right,,, I have to come back home early to pack my luggage.
I'm going to go on a journey tomorrow!
