So you are smug and miserable? And is terrible at playing instruments while claiming to be "cultured" and doesn't appreciate the people who try to be friends with you? Talk about being antisocial and misanthropic.
SQUIDWARD IS NOT A RELATABLE CHARACTER; HE'S MISERABLE, SMUG, UNREASONABLE, AND PATHETIC. FOR A GUY WHO CLAIMS TO BE "CULTURED" HE IS AWFUL AT PLAYING MUSICAL INSTRUMENTS AND DOESN'T APPRECIATE THAT SPONGEBOB AND PATRICK ARE TRYING TO BE HIS FRIENDS WHEN HE IS ALL LONELY AND BITTER.
