John contacted a contractor about having a renovation to his house. He mentioned about a water leakage on the ceiling would be the main priority to be fixed. The contractor assured him by saying "I am a water proofing expert. Water fears me!". Being satisfied by the contractor's assurance, he confidently handed over the upfront to him. Then, there was no written agreement made since there was a special bond between them. So, in order the renovation to start, he moved out of his house and lived in a service apartment. The question is that who is making the offer and who is accepting the offer. And whether is there any legal binding contract between both parties assuming it is a valid offer and acceptance.
