Today was a hard day... Ochem exam at 8 am this morning, then straight into the library for MCAT studying, doing two day's worth work after putting one off to focus on ochem exam prep. I stay until starving, and decide it's time to ride home for lunch. I come out of the library to see a flat on my road-bike and had just used my last spare tube... I pull the wheel off and find the hole is patchable, so I patch it. put the tire back one, and it deflates... I pull it off again and find another hole I missed, patch it, and thoroughly inspect the inside of the tire to make sure there wasn't a thorn or something stuck in it... nothing. I put the tire back on, pump it up, give it a few minutes to check it... It deflates. ****! The walk home is a couple of miles. I pull the tire off again, check the patches, okay, the first one failed... I can fix that. I fix it, and I'm on the road. I get home, make a sammich, finish my section review, and off to work I go. I got home 15 minutes ago, and class starts in 8 hours... Surprisingly though, this is one of those days that makes me feel like I'm exactly where I'm supposed to be.
