Gifts are another example of this. Gifts are a symbol of time. Time and creativity to think of and find the gift. Time it takes to earn the money to buy the gift, all increments of time.
When one avoids confrontation, one might justify the avoidance with a phrase such as, "He's not worth it." Which is another way of syaing, "He's not worth the time." A statement of the prevelance of time in the daily unconcious. That one doesn't want to engage in something that will have a negative outcome on time. "Time heals all wounds." Time can solve all problems. Time is what life is all about.
If ever a fondest player
For other weal availed on high,
Mine will not all be lost in air
But waft thy name beyond the sky
Twere vain to speak to weep to sigh
Oh, more than tears of blood can tell
When rung from guilt's expiring eye
Are in the word farewell, farewell
These lips are mute, these eyes are dry
But in my breast and in my brain
Await the pangs that pass not by
The thought that ne're shall sleep again
My soul nor deigns nor dares complain
Though grief and passion there rebel
I only know we loved in vain
I only fear, farewell farewell
Lord Byron
