Final answer:
Offeree's silence is not typically an acceptance in contract law unless it's accompanied by actions that indicate acceptance, such as the use of goods or services provided with the expectation of payment. In legal contexts like the right to remain silent, silence does not constitute an invocation of Fifth Amendment rights without explicit invocation.
Step-by-step explanation:
Generally, an offeree's silence is not considered an acceptance of an offer in contract law. The offeror must receive some communication of acceptance from the offeree for a contract to be binding. However, there are some exceptions to this general rule. If an offeree takes benefit of services or goods with the knowledge that they were offered with the expectation of payment, then the offeree's silence (accompanied by the acceptance of the offer's benefits) can sometimes be interpreted as acceptance. This is often contextual and depends on previous dealings or agreements between the parties. Furthermore, in law enforcement circumstances such as the right to remain silent, as outlined in Berghuis v. Thompkins and Salinas v. Texas, an individual's silence is not treated as an invocation of the Fifth Amendment's protection against self-incrimination until it is expressly invoked.
