‘Life of Riley‘ was a phrase I heard many times when I was young. It meant I had good or comfortable life.
Other phrases used on a regular basis were:
Money for old rope
Cheap at half the price
A flash in the pan
Under the weather
Jumping the gun
Keep your shirt on
Raining cats and dogs
All at sixes and sevens
Take it with a grain of salt
Dressed to the nines
What phrases do you remember from your young life?
