It’s no use crying over spilt milk.
It’s better to be safe than sorry.
It’s easy to be wise after the event.
It takes two to tango.
Ignorance is bliss.
If wishes were horses, beggars would ride.
It’s never too late to mend.
It’s not over till it’s over.
If you can’t beat them, join them.
If it ain’t broke, don’t fix it.
