I don't remember your name

I've seen that look before.
They come over,
They say your name,
You see, they've been watching your eyes
They've spoken with your eyes in their mind
They see them as kind
They make their mental assessments that you're it!
You're what they were looking for in their leisure hours
You, you, you
The you that will save them
The you that will tuck them into your arms, sail away to some fantasy land with dragons and unicorns and maybe a princess.
Then you talk.
And you say something quite ordinary
And you see it
That look in their eyes
A shift
A telling
A walking away
Maybe they've walked away
The bothering of you...
Obviously,
With all the strength it took them to come over,
Was wasted energy,
Because no, you can't save them.
Not when you came to save yourself.
