Stupid Gryffindors

Seriously, Gryffindors are stupid enough to make fun of their own housemates, not bother getting a teacher when they know that someone's in danger, and to nearly get themselves killed because they don't bother to come up with a plan? Companion piece to "Friendly Pain" as an AU to the troll incident in JKR's HP&tPS. WARNING: slight Ron!bashing and Gryffindor!bashing.
