Do you think it's true that people that enter your life are either a lesson or a blessing?

Some are a lesson on how to dispose of a body.

The ones who make an impact.
Some are just people who come and go it's like they were never there.

I’m seriously starting to wonder about that .... great question.

Nope, some are just there to do laundry.

Well I think there is some truth to that.

She was a blessing to me. I was a lesson to her.

Some lessons are better not taught in this case

Nope.
Most just breeze through on a limited timeline and their impact is negligible.
There are bound to be the odd one or two that will stick around for a while and either positively or negatively impact your 'present'.
But even then they won't last too long.

Either or

Nuisance.

I belive people come into your life for a reason how it helps or not is for you to know☺
