When is consent manifested?

Consent is manifested by the meeting of the offer and the acceptance upon the thing and the cause which are to constitute the contract.[1] The offer must be certain, and the acceptance, whether express or implied, must be absolute.[2] An acceptance is considered absolute and unqualified when it is identical in all respects with that of the offer so as to produce consent or a meeting of the minds.[3]
