(((Katie))) - I'm sorry that he's still out there, but I'm proud of the way you handled it. My dad saw me at my worst...living on the streets, looking pretty darned bad. I can imagine that buying me lunch, then dropping me back off in "the 'hood" was extremely hard on him. I hope your son finds recovery soon, but like (((Kitty))) said, we have to hand over our A's to a higher power and let them handle it.
Big hugs and prayers to you!
Amy
