Not Getting It

A conversation between a woman and someone she just met.

Him: "So, are you pre-op or post-op?"

Her: "Does it really matter?"

Him: "I couldn't tell. I thought you are a woman."

Her: "I am a woman. That's the point."

Him: "You took it wrong."

Her: "No, you meant it wrong."

Him: "I was only asking."

Her: "Something that's none of your business."

Him: "It is if I like you."

Her: "Then, are you pre-op or post-op?"

Him: "What the hell does that mean, I'm a guy."

Her: "Yeah, that's the point."

Him: "But I haven't had surgery."

Her: "Really, could have fooled me. I thought you were a guy."

Him: "I am."

Her: "As I'm a woman."
