That's what friends are for

Dear Dr. Rebus,

    I have a buddy who's a lot of fun to hang with, but he is a little thoughtless and selfish at times. Just recently he borrowed my car to go to the Indian casino for a weekend and when he gave it back to me it had no side view mirrors and the bumper was all scratched up. Plus I just got a bill from the city for the two tickets he got for running red lights. I don't know what to do about it. What do you think?

    Signed,

    Friend At Wit's End
