Analysis of If we must part

If we must part,
Then let it be like this.
Not heart on heart,
Nor with the useless anguish of a kiss;
But touch mine hand and say:
"Until to-morrow or some other day,
If we must part".

Words are so weak
When love hath been so strong;
Let silence speak:
"Life is a little while, and love is long;
A time to sow and reap,
And after harvest a long time to sleep,
But words are weak."
