1 Serron: Sometimes I forget you're a tree, Quercus.
1 Quercus: No problem.
2 Iki Piki: How could you forget he's a tree? He looks like a tree!
3 Serron: I just treat everyone as a person.
4 Iki Piki: You mean as someone to rip off.
4 Serron: Sometimes I even forget you're a human.

I wrote this strip thinking that Iki Piki's obvious non-human appearance would make the last line funny, forgetting that in cyberspace his avatar is basically a human shape.

When I realised my error, I thought it might ruin the joke, but on reflection I think it might make it slightly funnier.

Maybe.

I hope.
