Memento

[TranquillityBase]

Careful there Tim-
yer very close now... very minor edit suggested. Moving up 'this skull' reconates better with 'share' when it has  more space, I think. Leave out 'their', it oddly de-personalizes- 'light and shadow' by itself works much better, for this reader:

It’s a universe we share. He is father to my grief
and I am father to his memory, this skull
a jagged memento of light and shadow.

This really improves the sonics.  Thanks yet again.  Yes, I was unsure about "their", now I see why I should have been.  Guess I wanted to point them more at "grief" and "memory", but I don't think leaving it out prohibits that.

Should I maybe end on a high note, e.g. "shadow and light"?
