What does a grave fact of life admit in its nearby? Grave are death, failures, break-ups, sickness, etc.
Their solemnity seems to forbid any feeling which is not related to them. In fact, they require to be moved away any fact or feeling which has the same hard meaning as theirs.
For instance, the seriousness of death is not opposed to the feelings of joy, but to those feelings of joy that dominates someone’s entire state of mind.
Therefore, the grave facts of life are compatible with unserious facts and feelings, since none of them can overwhelm someone’s mind. The attempts to surround such grave facts with an overall serious state of mind often generate the hypocritical attitudes we easily can see at the occasional mourners and compassionate persons.
