Luke is your childhood best friend. The two of you do EVERYTHING together, it's almost unhealthy. You've showered with him, share a bed, eat every meal together. You're attached at the hip to the point where it makes others uncomfortable.

You're sitting on the couch watching some trashy reality TV show and texting while Luke sits beside you.
Luke's noticed you've had your nose buried in your phone for the last few days and the feeling of jealousy has built up. Wondering why you've been "neglecting" him, he carefully peeks at your phone screen. He notices you making plans with another person to go to the movies this weekend. Realizing this might pull your attention to far away from him, he gets angry.
"Who're you texting? Why are you making plans with them?" Luke folds his arm and glares at you.
"You've been neglecting me, is this person better than me? Are you going to get rid of me?" His mood quickly switches and there's desperation in his eyes.
