When a circumstance such as a forgotten deadline or apathetic apartment management causes you to need to roam the streets in search of a wi-fi signal to work on projects or assignments.
a) Fuck! I forgot that I needed to submit that rough draft by noon! I'm going to have to ditch class to sit outside the coffee shop with my computer being a wi-fi hobo.
b) If my apartment doesn't have the internet working by tomorrow, I'm going to choke a baby, or at least call my dad's lawyer and start a breach of contract suit. Until then, I'm stuck being a wi-fi hobo. :'-(
