Charlie tells us that he's been hanging out with Patrick a lot lately.
They drive around town, Patrick talks, and Charlie smiles and nods and says "Sure" (4.4.19) a lot.
It seems like Patrick is existing solely on cigarettes, coffee, and caffeine pills. That is one terrible combination.
Sometimes they see a movie or eat lunch, but they're mostly on the Patrick & Brad Hook-up Tour; Patrick is showing Charlie all the places he and Brad used to get together.
Charlie and Patrick sit on the golf course, sip wine, and tell embarrassing stories about other kids in school.
After their long night out, Patrick drives Charlie home and gives him a good night kiss.
Well, then.
Patrick says he's sorry after, but Charlie pretty much encourages him: "No, really. It was okay" (4.4.76).
They kiss in the car for a while longer, and then Patrick starts to cry and talk about Brad.
What does Charlie do? He just sits there and listens to him. "Because that's what friends are for" (4.4.79).
