Final answer:
A promise in consideration for 'the happiness you give me' may not be legally sufficient consideration. Consideration in contract law requires something of measurable value to create a legal contract.
Step-by-step explanation:
According to the given information, a promise in consideration for 'the happiness you give me' may not be legally sufficient consideration. To be legally enforceable, a promise needs to have some measurable value or benefit to both parties involved. The concept of consideration in contract law refers to something of value exchanged between parties to create a legal contract.
In this case, 'the happiness you give me' could be considered subjective and not easily measured or quantifiable. Therefore, it may not meet the requirement of legally sufficient consideration in contract law.
An example of legally sufficient consideration would be if a person promises to pay another person a certain amount of money in exchange for a specific service or product. Both parties are giving something of value, which makes the promise enforceable.
