What should I do if I meet a friend and borrow a car?

Spend money to eliminate disasters (⊙ o ⊙)! Just say, oh, I'm so sorry! I need to use my car or borrow it from others that day! And say, why don't I rent one for you? Better than my car! (* _ _ *) Hee hee ... I don't think he will let you pay! If you really want to pay, then spend money to eliminate disasters! It shouldn't cost much a day! It is ok to be a gift.
