・wait for the timing
・consider the timing

我正在尋找合適的時間告訴我的父母，我想讓他們買一些東西。
I'm waiting for the timing to say that there's something I want my parents to buy.

be waiting for the timing to～ = 等待時機做～，尋找合適的時間做
want 人 to～ = 希望（人）去做～，為我做～

ex. 我正在尋找合適的時機告訴父母我的請求。
I'm considering the good timing to say my parents about my favor.
consider =仔細想想，考慮
favor = 請求
