old-time

I lent him the money for old times’ sake.

念交情，我把钱借给他了。

They were chatting of old times.

他们畅叙过去时光。

The good old times are over.

好子已经过去了。

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

走吧，咱们现就出去吧，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!

我走时候，他们正桌上又唱又跳，开心极了。
