A Big Fly Trapped In A Spider's Web

I saw a big fly floating in mid air but didn't notice it moving. A closer look reveals it's been dead for a while because it was trapped in a spider's web.

​The spider was nowhere to be seen
and the fly looked like it was not harmed a bit.
Surely it died of hunger and thirst.

Since there's no spider who owns the web that trapped it,
I got it with some stick
and placed it in the web of another spider nearby.
The other spider was alarmed when it saw me,
but in just few minutes,
it enjoyed the one big, delicious meal of a fly.

The fly was an adult one,
and it was unexpectedly trapped in a web
while it was flying about.
And surely it struggled to free itself
the very moment it was trapped,
but it failed.
That's part of life,
whether you're human or an animal.
You'll never know what lies ahead of you
unless you become a prophet
then you'll see the future.
But still,
there are lots of things happening
that you wouldn't expect will happen to you.
You're alive in one moment,
but the next,
you're dead.
