I found a set of keys lying in the street. They had one of those yellow rectangular key tags from a Honda dealer in another state and the tag read, "Control Room Kia Bldg" and instructions as to which door they were for.
I called them and instead of gratitude I got confusion, put on hold, and then requested to mail them.
I put a sign up near where I found them and stewed over the weekend.
Yesterday I decided to be a good citizen and mailed them and am out just $2.07 which is a small price to pay forward.
