Hello Jenny,

To start, I very much like the subject matter, though if I'm being honest, I feel it started to drift away by the seventh/eighth stanza, and lose it's focus. I also feel that from the fifth stanza onwards, the rhythm was quite confused, with one line in the stanza being far longer than the other. This like, for example:
"It doesn't matter if we walk on the beach or shoot some pool,
As long as I'm with him I'm perfectly cool, "
Could've perhaps been shortened into something like this:
"We could walk on the beach, shoot some pool,
As long as I'm with him I'm perfectly cool,"
I'm of course not trying to tell you what to write, or how to write it, but give suggestions that may help in the future for a smoother flow. With this line it just felt as if you wanted to have your cake and eat it too (an expression I've never understood, because of course one would like to eat the cake they have).

Despite what I've written, the piece did have an ease about it. A charm. A calm, blissful joy. This is the first poem I've ever read by you, and so far I like your work, I just believe that with a few tweaks to your approach, your work would be even better.

P.S. Be careful of repetition. Sometimes it's great and can really work, but other times it can be jarring. I feel you may've used the word 'day' a tad too much in the first few couplets

Good rhyming. Again beautifully written.
