Use of Nagara if two people are involved


Can you still use _nagara_ if two people are doing the actions? For example

> I was reading while he was making dinner.




According to A Dictionary of Basic Japanese Grammar (Seiichi Makino and Michio
Tsutsui):

> nagara cannot be used when the subjects of the two actions are different. In
> this case aida is used.

Here's my attempt at your sentence:

> 彼{かれ}が夕食{ゆうしょく}を作{つく}っている間{あいだ}、私は[本]{ほん}を読{よ}んでいた。(or [読書]{どくしょ}をしていた。)  
>  kare ga yuushoku o tsukutteiru aida, watashi wa hon o yondeita. (dokusho o
> shiteita.)
