You can go

I ought to water the plants

Oh, don't you? The plants should be missing you

They certainly do

More silence

I am wondering why my plants are so sensitive to human presence, I meant, my absence. Have you come across such plants elsewhere, love?

Did your mind just choose to say 'presence' instead of absence?

Apparently it did

I haven't come across such a mind, oops, I meant plants. What do they call it, freudian slip, eh? 

What sort of a mind?

One that rarely fumbles under the weight of complicated processes

But I did fumble

Which complicated mental processes was I referring to?

You tell me

We know what they are

Do we?

Yes. We do. Complicated processes like juggling, writing simultaneously with both hands and the like. It boils down to handling more than one thing/person at a time. 

Yeah, I do remember talking about it sometime

What did I just tell you?

Some more silence

But the plants!

Yeah! The plants can't stand your absence though they seem to be able to take your obsession with them.

My obsession with them? 

Yes

It's just that I love them!

Well, there isn't much of a difference. One can't differentiate between the neurotransmitter release pattern of Obsessive Compulsive Disorder and love..  Honey, you can go 

Can I? 

Yeah. 

And he let her go.
