Longer summary
This post is a fictional story about a Jewish vampire attempting to suck the blood of a non-observant Jew during Passover. The narrator tries to dissuade the vampire by claiming his blood is chametz (leavened food forbidden during Passover) due to eating bread. The two engage in a humorous debate about Jewish dietary laws and their application to vampirism. The story ends with a twist when the narrator's attempt to escape into his house fails because the vampire is 'not so frum' (observant) and can enter without invitation.
