Now here's a form of verse I have never attempted to write. All my poems tend to be as couplets or four-lined quatrains. Here, I felt inspired to write a tercet or a three-lined stanza. It so happened that the first verse popped into my head as three lines. I could have modified it into a couplet or a quatrain, but thought to leave it as it is and go with the flow.
What happened is I ended up writing each stanza as a tercet in a aba rhythm. I now know this is called an enclosed tercet (googled it). There you go. I've learnt something new today.
