Finished up a run this morning and an older runner approached me. He saw me running and was complimenting on my speed and form. I passed him earlier and gave the usual "nice job". I began talking with him and turned out he was a former D1 athlete and had some great Boston times. I felt like an ass. I've seen the guy before, but usually I'm rushing to get my run in and done and never stick around to socialize with the other runners there. Was a humbling experience. Wished him well and left after our 30 min talk. Have any similar stories?
