“Can I join you for lunch?”
It’s not really a request
To find something to munch.
Instead, something I like best:

Space Occupancy with you.
That’s what “Can I join?” means.
It’s not eating that I want to do.
It’s seeing you live, not just in dreams.

It’s occupying nearly the same space
As you are operating in.
It’s being in the same place
At the same time that makes me grin.

“Can I join you for lunch” is not an invitation to eat.
It’s a request to be near you, beside you, that makes me complete.
