Seriously.

Two men have been living together for a while. They have a great relationship. All of a sudden, one day, one man left the other.. for the other's best friend (and neighbor!).

The other tries to get over it. He goes through different companions, and then goes through that 'I don't need anybody' phase. After a while, the best friend and man come over to go through a weekly ritual.. acting as though nothing ever happened.

The other freaks out and starts begging the man to come back to him. He tells him everything will change, and be different. He makes all kinds of promises, but the man looks at him as if he's not making any sense.

As the day moves forward, the man decides he wants the other back, too. He confesses to the other that the only thing he wanted from the neighbor... was the cookie in his pocket.
