I immediately fished it out (and then immediately washed my hands). While my cell phone remained lit momentarily, the screen soon turned off, followed by the key pad. Despite my efforts over the next couple of days, I was unable to generate any sort of response from it after that.
Seeing as how cell phones are expensive and I am, for all intensive purposes, broke, it became clear that I would have to do without a cell phone until my next paycheck, which arrives in 2 days. I have gone ahead and ordered a cell phone which will hopefully arrive by the end of the week, but before then, I will include some anecdotes from my adventures in unavailability.
