Triangle.

This is something you rarely see in these write-offs, either poetry or minific, but one I've advocated in the past: use some sort of word gimmick. There are lots of ways to do it. This is a good one, by modulating the number of words per sentence/line (what I expected here is to have every successive line to contain one less word, which isn't the pattern, just that each line never has more words than the one above it). Another is to make every sentence start with the same word that ended the previous one. Another is to start each sentence with the next letter of the alphabet. There are lots of things you can do like that, and while they're not usually meaningful, they do provide a fun quirk and can add a little whimsy, and they can help prompt a writer into creative language use and perhaps even overcome some writer's block.

The sentiment here is a nice quiet one as well, where someone lets a fairly mundane thing overwhelm his capacity to do something he really should have. That's something I certainly fall victim to.

Can I tell the tale in eight words?

Or will I need just barely seven?

At this rate, there's no space

To make apology to dad

For letting it slip

Too long, and

Trailing off

Sadly.
