<human>: So a little back story first, im a full time cyclist and a full time student. You can see how those don't work together. My buddy invited me to a party to take off the load a bit. The next day I woke up completely incoherent and stumbling only to realize that I had scheduled a ride for 7am with my trainer. I grabbed my stuff and headed out. My trainer noticed my obvious lack of effort and blasted look on my face. He told me we'd reschedule for the next day. 

Oh boy. 

So today, I suited up all ready to go and rode three-quarters of a mile when I heard a loud POP. A large construction nail the size of my index finger had embedded itself in my tire. I rolled my bike back home and began to switch the pedals to my other bike seeing as I had no spare tires. I grabbed my wrench and started on the first pedal. Somehow in my fit of red-faced brutality on the wrench, my hand slipped and my finger was sliced open like a thanksgiving ham on my bicycle sprocket. I panicked and a episode of dry heaving and blood everywhere, I mean everywhere, I rushed to the urgent care and I payed twenty-five dollars to have them soak it in cleany-stuff and put a fancy band-aid on. 
Now im stuck with a flat tire, a lacerated finger and a very disappointed trainer.

Summarize the given text in a few sentences.
<bot>: rescheduled a bike ride b/c hungover, ended up with no clear way to jerk off and a flat tire.
