Unprepared

I thought that I was unprepared
In case the day got colder.
I should have brought a sweater 
I could toss across my shoulder.

I wasn't sure I'd brought enough
To read to be fulfilling
In case some plans fell through and there
Was time that needed killing.

I thought I might get hungry
And forgot to bring a snack,
Though once I'd had that thought, it was
Too late for turning back.

It turned out I was warm enough,
Not hungry and not bored,
So luck was on my side,
A most mysterious reward.

For though the Girl Scouts tell us
We should always be prepared,
Without such luck we never know
Just how we might have fared.
