<human>: Bonus question: My granparents own the car and I talked to them both about it at the same time and they agreed to give me the car so that I can use it to get back and forth from community college. My grandmother owns a car and it is primarily my grandfather's mode of transportation right now. He has started getting around using a senior citizen transportation service, so he no longer uses the car. He hasn't driven the car in months and it is usually months at a time before he ever drives it. Now, after all the discussion about this topic, he is acting as if me coming to get the car in 2 weeks is a huge surprise and that he never said I could have it. I have no idea to go about this. Suggestions?

Can you give me the gist of the text in a nutshell?
<bot>: Grandfather said I could have his car that he never drives and now he says that he drives it all the time and that he never said I could have it. What do?
