Perpetual Immaturity

So why is it that everytime a woman I'm "involved" with says she's going off for a night with the ladies, I naturally assume the evening will be peppered with exchanges of this ilk:

Girl #1: Cool skirt.

Girl #2: And I love those shoes.

Girl #3: The movie starts in a half hour.

Girl #4: To kill time, should we all make out?

Girl #1, #2 and #3: Most definitely!

Too much porno? I'm guessing too much porno.
