I love things like that, it gives the idea of the two people being so absorbed in each other that they pay no attention to everything going on around them, like the world goes on as normal while they together feel anything but normal. Even though the poem says they were jusk talking from the few short sentences and the title you can tell there's a deep love between them. I may be reading too much into it but that's how it made me think.
Time's sand scrammed
I didn't think those lines were that good, well actually I thought Time's sand was a great start and then I didn't like scrammed, it just seems like an ugly word to me in such a lovely piece of writing. That's just a little personal opinion though. Tender moments is a great title, it gives a lovely feel to the poem before you've even read it.
So overall it's good for such a short poem, sweet, clear and to the point.
