a good scout
An honest, affable, reliable, and trustworthy person. Your dad's a good scout, you know that? He's helped me out of so many jams without even thinking twice. Eric's a good scout, so I'm sure he'll do the repairs for a very fair price. Thanks for being a good scout—I know I can always count on you.
