So last night...I go out to the garage to top off the air in the tires on the commuter. It's about 10 at night, I'm exhausted, and I really just wanted to go to bed. My front tire was flat.
No problem...I'll just ignore it and take DH's bike in the a.m. It's not like he'll be using that bike tomorrow. I'll fix the flat tomorrow.
So, I go into the laundry room, where his bike is. Pump up the tires. Easy peasy. Done in a flash and I'm ready to go.
Oh, wait. It doesn't have a saddle bag. Need a saddle bag. I'll transfer the one over from my bike.
Oh, wait. It has a clip for it's own quick release bag on the saddle rails. Look for the bag. Can't find it. I'll remove the bracket.
(sound of clock ticking.....)
Finally! My saddle bag is on!
Oh, wait. I need a light. It's still dark in the a.m. I know. I'll just transfer the lights over from my bike onto this bike. Take the lights off. Arrrrgghh!!! Too tight on the handlebars. The cables from the brakes, the shifters, and who knows what else means I can't set this light up on this bike. It just beams up into space.
Grrrrr.... Well, I'll use DH's lights. He won't be using 'em tomorrow and they should have a charge.
Find lights. Put lights on. Sound of clock ticking.
There. Ready to go.
Arrrrrgghh!!!! DH has Crank Bros. pedals on this bike!!! I use SPD's!
Ferget it. I am NOT swapping pedals. I could have changed the stupid tire on my own bike 3 times in the amount of time I just spent futzing around with his bike.
Fortunately, DH heard my meltdown in the basement and came and changed my flat front tire for me. I put my own lights, and my own saddle bag back on MY bike, and that's what I rode this a.m.

e.t.a.: This is why people don't like bike commuting. Sometimes, it can be such a p.i.a. to get ready. Sigh.
