A convenient truth

Begine with the truism:

A guy is only friends with girls he wants to bang, or

Friendship with Girl --> Desire to Bang Girl (A)

From (A) we deduce that:

A guy is never friends with a girl he wouldn't bang, or

~Desire to Bang Girl --> ~Friendship with Girl (B)

Clearly, (B) is also a true statement, as it is the contrapositive of (A).

The following statement is more difficult to ascertain as self-evident:

If a guy is not friends with a girl, he wouldn't bang her, or

~Friendship with Girl --> ~Desire to Bang Girl (C)

Maintaining (A) as true, (C) sounds like it could hold up as well. However, to assume so would be logical fallacy. In fact, (C) is the negation of (A), and so axiomatically cannot be true.

Now, even though we know that (C) is definitively false, it's sometimes fun to provide counterexamples to help us understand why this is so. It only takes one counterexample to disprove an argument. A counterexample to (C) would be Marisa Miller: I am not friends with Marisa Miller, but I definitely have a desire to bang her brains out.

On a personal note, I am friends with A LOT of girls.

Thus ends the lesson.
