Heh? Perhaps it is because I am a woman and also a woman who rides (a lot), but it seems apparent to me that this "wrath" you speak of is completely separate from the bad reputation being given to the sport of mountain-biking. Perhaps, these friends you speak of have deeper relationship issues, are being flakey or irresponsible to what their significant other thinks has been agreed upon as a mutual priority? Maybe they want to spend more time together? Who knows? Unless you ask. It could be many things that invoke the annoyed wrath in this case, not just cycling. When in doubt, tell your friends to invite her cycling on occasion, you can play hooky together. Isn't that the goal, after all? Bringing cyclists together?
