I lent him the money for old times’ sake.

念旧日的交情，我把钱借给。

The good old times are over.

好日子已经。

They were chatting of old times.

们畅的时光。

Come on, let’s go out now—you can do the housework any old time.

走吧，咱们现就出吧，家务你什么时候都能做。

When I left them they were having a high old time singing and dancing on the tables!

我走的时候，们正桌上又唱又跳，开心极。
