When my cats are home alone, if someone drives up and opens their car door, they get inside. They also leap into moving strollers (with babies inside). Who knows what they'd do if someone came to the door (sigh)
Antisocial means having no remorse for committing murder so I hope you are not antisocial! Look up antisocial personality disorder!) it's a big difference people who don't like socializing are introverted NOT antisocial!
