Still Upset

I'm still so mad at myself for not being able to fix my bike on the fly yesterday. I really should have been more prepared. 

But I think what's also still getting under my skin is that I couldn't fix it even after getting the appropriate tools from the bike shop. 

Why don't I know how to change a flat tire even if that flat tire is on the back wheel? Why can't I remember the way that the change is supposed to go over my derailleur? And why didn't I know that derailleur was spelled so strangely? 


I'm clearly not a real biker... but I want to be so badly.
