The context of the following conversation is Addison knew one of his friend's secrets but let it slip to his other friends, Matt and Tom.:
Addison says Well, Matt and Tom are being real jerks again..
The friend responds Matt I can believe, but Tom too?  What happened?.
Addison responds Well, I let it slip that Peggy-Sue has a crush on Carl.  So, when Matt and Tom heard the news, they ran off and told Carl..
The friend responds So what's the problem? Matt and Tom were just playing like Cupid..
Addison responds First of all, Peggy-Sue told me never to tell anyone. So I am so busted, but those jerks spray-painted "Peggy-Sue Love Carl" all over outside of the math class windows.  So Peggy-Sue and Carl, who were sitting next to each other in the front row of Math class today, found out when Mr. Beevers raised the blinds 5 minutes into class.  Imagine, being forced to sit in embarrassment for 40 minutes while Mr Beevers refers to the graffiti all period.  Peggy-Sue is going to kill me!.
The friend responds Look on the bright side, the windows in that class are finally gonna get a good washing....
