Let nature take its course,
Echo,
Improvise,
Anytime, anywhere,
Go with the flow,
Suit sb.' s talent,
Shape with things,
Follow the market,
One voice after another,
Casual,
Since the high level is a low level,
When in Rome, do as the Romans do,
Go with the flow,
A casual glance,
Measure the situation at any time,
Explain in words,
Random stall
