我在聚会上遇到了一个老熟人。

I met an old acquaintance at the party.

老熟人的名字怎么都想不起来？

Or struggled to remember the name of an old acquaintance?

我在瑞士度假时巧遇一位老熟人。

I fell in upon an old acquaintance of mine while on holiday in Switzerland.

魁刚也异常健谈，两人一起回忆起以前的任务，还有老熟人。

Qui-Gon had been in a rare talkative mood, and they had remembered old missions, old acquaintances.

老熟人的那种最明显的外貌特征让他不能再无动于衷自己的回忆。

The most formal of old acquaintances could hardly have recalled himself in a more indifferent manner.

他上百货大楼时，总喜欢靠在柜台上和女店员像老熟人一样聊聊，问些 套 近乎的问题。

If he visited a department store it was to lounge familiarly over the counter and ask some leading questions.
