Help dealing with an annoying xian!!!!

[in_his_name_666]

Hello again everyone,
Anyone have any Idea's on the best possible way to deal with my friends mom who is a christian. She is one of the self righteous, know all, thinks they are better than everyone else types. She thinks that because she goes to church once a week, she can treat anyone however she likes. Its getting on my nerves and honestly I am sick of it. I just need some ideas just in case I were to talk to her again because I like to hang out with her son once and a while. Any advice would be much appreciated.

Hail Satan!!!!!!
