Maybe I'm just mature/old before my time (avatar quote), but I've usually had a good sense of how important/dramatic something is, and so have the people I've hung out with. I can't stand people who make drama over nothing. Or am I just the exception?
Parents seemingly embarrassing you, showing you up, or younger siblings stealing the limelight (ala Inbetweeners) is to me much closer to real life. The scenes with Simon and his younger brother especially.
Might've just been me, but I lapped it up, it was gorgeous.
