The idiom "have one’s cake and eat it, too" means wanting to have or enjoy two things that are contradictory or mutually exclusive. It refers to the idea of wanting to eat a cake but also wanting to keep it for later. It is used to describe a situation where someone wants to have the benefits of two things that cannot be had at the same time.
For example, if someone wants to quit their job but still wants to receive their full salary, they are trying to have their cake and eat it too. It is impossible to quit a job and still receive a full salary, so this is an example of someone wanting two things that are contradictory.
Another example could be if someone wants to go out with their friends every night but also wants to get a good night's sleep. These two things are contradictory because going out with friends often involves staying up late and not getting enough sleep.
Overall, the idiom "have one’s cake and eat it, too" is used to describe situations where someone wants two things that cannot be had at the same time. It is important to understand this idiom because it is commonly used in English conversation and literature.
