You will get into hot water if you commit the same mistake again.

One should not indulge in <u><em>tall talks</em></u>.

To give a rap on the knuckles

He <u><em>went back on</em></u> his promise to vote for me.

Manoj always <u><em>keeps himself to himself</em></u>.

To fly off the handle

In double-quick time

We must always <u><em>bear in mind</em></u> that only hard work leads to success.
