Drinking Party Hopping

Just after promising with former boss to go drinking, someone invited me a drinking party with duty. I cannot refuse both of them; finally I decide to go both of them after telling my situation about double booking.
At first I join the party with duty and drink some beer, and I move to drinking with former boss. We also go to a pub where we can collect stamps of Guinness :-) I really enjoy the meeting; drinking, laughing, and playing darts. Let's play darts again! (to former boss & former colleague)
