Take the heat?

Ahead of the curve?

Written all over it?

Don’t take it to heart

The penny has dropped

Heads I win, tails you lose

Damon and Pithiest

No strings attached?

Last time I checked

Informed decision?

Well-heeled area?

Piece of cake?

Safe and sound?

Small beer?

耶鲁校友谈美国老师的教育方式

All comers?

Don’t wear it on your sleeve

Off the table?

An idea whose time has come

Have baggage?

Rubbing it in

That particular bridge?

A qualified ‘yes’?

羊群心理 Herd instinct

Get it out of your system

Straws in the wind?

Deer in headlights?
