Perspective. If you were to look up the definition and focus on the non-artistic aspect of the meaning, you would find descriptions like ‘the facts known to one … the faculty of seeing all the relevant data … a mental view or prospect … understanding from a certain point of view’. And the cold hard truth is, whether specific to a certain situation, or due to a lack of maturity or experience, we don’t always have it.
If you have children (especially teenagers) or if you remember your own childhood (especially the teenage years) you understand exactly what I mean. What appears to be isn’t always what is.
