Imagine inviting that lot to your house for dinner! By the time they left your fridge would be emptied out, your belongings would be broken, your eardrums would be burst, Sue will have filmed you, Noel will have stolen your knickers, you'd have to scrub the house for weeks to get rid of the dirt from their feet, your house would smell like sweat and old pie meat, they'd forget a few kids at your house and you'd be mysteriously pregnant just from being around them.
Not to mention they wouldn't fit around a regular persons dining table
I don't think they have friends anyway besides the Walkers
