It's people like that old lady who give us a role model to look up to with her true actions of virtue and integrity. We all need to understand that learning is a lifelong process and we should always treat learning something new with the same mindset that we've had since we first started school. That is one of no worldly biases which can distract us. People who think they can look down on other simply because of a status quo such as age are pretty immature themselves in terms of seeing things in this world.
