Penny-wise and pound-foolish

One swallow does not make a summer

Once bitten, twice shy

Nothing comes out of the sack but what was in it

No longer pipe, no longer dance

Never try to prove what nobody doubts

Neither fish nor flesh

Much ado about nothing

Men may meet but mountains never

Many a good cow has a bad calf

Lost time is never found again

Little pitchers have long ears

Like father, like son

Let sleeping dogs lie

Keep a thing seven years and you will find a use for it

It is never too late to learn

Iron hand (fist) in a velvet glove

If you sell the cow, you sell her milk too

If the sky falls, we shall catch larks

Hunger breaks stone walls
