One of my original riding friends from 2 years ago "lost interest in street riding" and only does track now and doesn't talk to us anymore. He used to talk so much about how great friends we are and how glad he was that he met us.
Meanwhile, my other riding friend never said such things. He's just always there being a good friend, making time to ride with me when he can, even after he got a busier job. Still talks with me even if we go a month without riding together.

Beware the ones who run their mouth a lot.
