One up, one down

 
Only one "lightbulb moment" here, but it's really the only one I still wonder about.
Prompt #19: Lightbulbs

In my head
it all made so much more sense,
no dangerous tread
and certainly no false pretense.
Affection bred
in earnest, and with no expense,
but here instead,
alone, and no new promise since.
It's easy dread
can turn behavior rather dense,
and easily said:
one more mistake without defense.
