Take the lead

My son's schoolwork has gone to pot. He really lets me down

wish you a safe / good trip / journey

If you stand here looking down at the city. The wonderful scene will be in full view

You have to make good use of time. After all, every time counts

kill two birds with one stone (lit. one stone kills two birds)

What millions died that Caesar might be great

Kill two birds with one stone

to fall in love at first sight

smooth sailing (lit. single sail;gentle wind)

His business has gone off without a hitch

Time is money

make it at one stroke

I really have no idea what to do. Now I am at my wit's end

Once bitten, twice shy

The outcome of the election just bit the dust

A white complexion is powerful enough to hide seven faults

day and night

gnashing one's teeth;displaying extreme anger;fuming with rage between gritted teeth

(of parents) to bring up children for the purpose of being looked after in old age
