QY: Happy Friday， Donny! 你今天晚上有什么計劃嗎？

Donny: Hmm, not yet. What do you have in mind?

QY: Let's go salsa!! 我今晚要跟兩個朋友去跳salsa, 可他們倆是一對，我可真不想夾在中間，當大電燈泡--very bright light bulb!

Donny: I see. You don't want to be the third wheel.

QY: The third wheel?

Donny: Yep! Wheel is spelled w-h-e-e-l. The third wheel, 第三個輪子, it's a very colloquial way of saying a third person joining a couple in a social context.

QY: 沒錯！我就是不想當 the third wheel!

Donny: Exactly, you wouldn't want to bother any love birds, right?

QY: Wait! Love birds? 愛的鳥兒？

Donny:Yep! In English, we often use the word love birds to refer to a couple who are openly affectionate, especially in public. 就是大庭廣眾之下卿卿我我。你不想打擾這對love birds吧?

QY: 可不是嗎！不過這兩個人很配！They are a great match!

Donny: Oh that's nice! You can also say, they are a match made in heaven.

QY: A match made in heaven？ 那不就是中文里說的天生一對嘛！

Donny: There you go! Since you don't want to be the third wheel, I will go with you! But first, let's see what you learned today!

QY: 第一：電燈泡叫做：the third wheel;

第二，如膠似漆的情侶，可以說 love birds;

第三，"天生一對"是，a match made in heaven.
