I discovered tonight that the same person who stole my bike light most likely also stole my valve caps.
I bought them at Fiesta for $3 to adorn the crappy old Honda Civic that I bought from Roo for $400 in 1999. I had to push start it, simultaneously keep my foot on the gas and the brake when it was stopped so it wouldn't stall, and hold the windshield wiper switch up manually so the wipers wouldn't run all the time. The valve caps made me feel a tiny bit better about all this.
Eventually my parents bought me a good car and Eric bought me a good bike, and I happily transferred the caps to the bike just for that extra touch of coolness.
I don't want to get carried away with overwrought nostalgia and not-very-hard luck stories here, but I'd just like to point out that whoever stole my bike light and my seven-year-old, three-dollar valve caps is a pathetic piece of shit.
