Epoch Vector Variance

The time it takes to walk from downtown to campus is a rather flexible vector, if there is such a thing. For example, when I've been distracted by my favorite thrift store and the delightful elderly ladies within and consequently am late for a meeting with my academic adviser, the walk is excruciatingly lengthy. However, when I want to walk as a means of amusing myself until my fiancee gets off work so we can have a talk of a serious nature, I can't make it last very long at all. When I' m walking for the sake of pondering my musings over anonymous observations, it can take an entire day, and when I'm walking and talking with a good friend, well, that's when the real paradox occurs, for then, time ceases to exist.
