We get together a couple times a month for lunch , too . Today , we went out to lunch . Today , she kissed me . On the mouth . From shock , I just stood there , frozen like a zombie . She took this as permission or something and kept going . As gently as I could , I pushed her away .

Question: Why did the narrator suddenly freeze up ?
Answer: They were not expecting a girl to be there .They were not expecting a zombie movie to be on .They were not expecting a zombie to show up .They were not expecting an intimate moment .
