We had an older man in our group that would always set things up for where and when we'd all ride. He'd get irritated if a certain woman in our group who was faster would go ahead and ride ahead of the slower riders..

Over the past 4 years that we'd all ride together our grumpy older man started to become more irritated with people in general. He'd really become defensive and belligerant if we would ask about his food and drink intake on the rides.. but he'd always give out unsolicted advice all the time. He started to really become short tempered with all of us also so subsequently, our riding group has broken up except for my girlfriend and I. I'd still ride with him off and on approx year ago but he snapped at me while we were on a long organized ride.. I had no indications at all that he was upset or irriated but all of a sudden he had this angry outburst directed at me.... I decided that his friendship wasn't worth keeping and was very angry with him since we did have a friendship for about 4 years. The only bad thing was that we'd run into this man at the local coffee shop or on our local trails.
