Example: Roger found himself walking on eggshells when it came to telling his wife about his upcoming boys’ weekend in Las Vegas.
‘Walking on eggshells’ is interchangeable with ‘walking on eggs‘. Both phrases seem to have surfaced in the 1800s, but it is uncertain which came first. Both are purely descriptive in nature. You can imagine how cautiously you would have to proceed on eggshells. Equally, you can imagine how impossible it would be to walk on eggs without breaking them. Cautious politicians were often described as walking on eggs.
