The man with the book came back to my house. He said that he thought I hadn't understood his religion.
I explained quite politely that I understood his religion just fine, but I still thought it was a pack of lies. Then I warned him, again quite politely, that he was going to burn in hell for eternity unless he immediately converted to MY religion.
And I think I let my guard down, because he said that MY religion was the fake one. Now I'm not sure what to think.
Normally I would have spat on his garments and ordered him out of my house, but he actually made me wonder if he was right.
This is going to cause problems, I can tell already.
