It's been half a year since you were fired, and the leader always asks someone to inquire about you. How to reply?

Generally this situation is caused by two reasons. The first one is that he is watching your jokes. You should know that you are fired, so your relationship should be very bad. So he asked about you. I don't think he has any good intentions. The second reason is the opposite. He just wants to see how you are doing, and he wants to save you, but it's a little unreasonable.
