"Change is inevitable - except from a vending machine"

This quote by Robert C. Gallagher is an amusing way of highlighting the idea that modification is an inescapable part of life. It implies that no matter how hard we attempt, we can not leave the fact that things will always be altering. The vending machine is used as a metaphor for something that is static and unchanging, and the quote recommends that even this is not immune to the results of modification. This quote is a suggestion that we must be prepared to accept and welcome modification, as it is an inevitable part of life. It also works as a reminder that we ought to not end up being too attached to any one thing, as it is most likely to alter eventually. Eventually, this quote is a reminder that change is a natural part of life, which we ought to be prepared to accept it and progress.
