Pedir peras al olmo

to expect the impossible; **to expect the impossible**; **to ask the impossible**; **you can't get blood from a stone**; **don't expect miracles**

Pedir peras al olmo means to expect the impossible or to demand something that cannot reasonably be expected.

The expression may refer to people, institutions or situations.

It often suggests that the problem is not unwillingness but impossibility.

• expects too much from another person
• asks for something impossible
• has unrealistic expectations
• complains about limitations that cannot be changed
• forgets that everyone has their own abilities and limits

The expression is based on an obvious observation from nature.

Pears grow on pear trees.

They do not grow on elm trees.

Because the impossibility is immediately evident, the image became a perfect metaphor for unrealistic expectations.

The proverb has been part of Spanish for centuries and remains fully alive today.

One interesting feature of this idiom is that it often carries a tone of realism rather than criticism.

When someone says:

No le pidas peras al olmo.

they are often advising acceptance rather than blaming anyone.

The message is simple:

Some things cannot happen, no matter how much we wish they could.

Many languages have an expression for expecting the impossible.

English speaks of getting blood from a stone.

French uses demander la lune ("to ask for the moon").

Spanish chose a much quieter image:

asking an elm tree to produce pears.

The proverb survives because everyone immediately understands the impossibility without needing any further explanation.

Do not translate the expression literally.

English speakers would never say:

Don't ask an elm tree for pears.

Instead, choose expressions such as:

• Don't expect the impossible.
• You can't get blood from a stone.
• Don't expect miracles.

Although the images differ, the communicative purpose is the same.
