I still can't figure out, what's the connection between Butterfly and Guest.  It's irrelevant.. right?

I'm sorry, do I confused you? Well, for those who doesn't know, there's a saying in Indonesia that when you see a butterfly fluttering and stay on your door house, it might be a sign that there will be guest coming to your place.

It's like a butterfly is your private messenger. It would be so nice to have one. "Careful, people who you owe money come in..5 second, quick, fake death!" something like that :D

And Butterfly itself is a symbol for Soul. A transformation in Life. A  Hmmm... I still can't ..

MAYBE, The "Guest" is the butterfly itself!! AHA! I think I solved it. If any of you know the relation, do tell me. I'm sure sure, your conclusion is more relevant. :)
