Fleet

I go weeks at a time without spending a dime.
I am busy at home when the spending is prime.

I laugh remembering calls once cost a quarter.
Cash was paper & coin in banks’ brick & mortar.

An adaptable human can tolerate change.
Though, now, it comes in a wider spectrum of range.

See there’s Change in Life & change in your pocket.
Both can absurdly switch your course like a rocket.

So maybe small & lean living is the wiser tack.
Agility is ideal when under attack.
