found a disc with ink
So a few weeks ago I found a disc in the bushes while looking for a bad shot of my own. The disc had a name and telephone number on it, so I immediately pulled out my cell phone and gave the guy a call hoping that maybe he was still at the course, or maybe in the area and I could meet up with him and return his plastic. When I called the guy and told him I had his disc he was like " oh, yeah that disc, oh yeah, well I'll might be in the area next week, maybe I'll give you a call". He did not seem to give a $**t. Well three weeks have gone by and I still have not heard from him. Should I call him back and re-offer his disc to him, or should I just add it to my bag and forget about it? I do like the disc and it is quite useful to me on two of the holes at my home course. I tried to do the right thing, but he really seemed not to care. What is my next move?
