Paint the Town Red(carouse and have a good time)
How did you enjoy your vacation to Europe last summer?
It was marvelous. I'll never forget the time we had when we were in Rome. There was no end to things to see and do.
And how was the night life?
Great! We painted the town red the first three nights we were there.
Didn't that get to be pretty expensive?
I guess so, but we were so excited by all that the city had to offer that we went out carousing without thinking about the cost.
get to be = become, add up to
carouse = どんちゃん騒ぎをする
