If you're among the ranks of the super-disorganized, the idea of having guests over might make you panic. If you suspect your house is a certifiable disaster zone, it's nerve-wracking to think of the Joneses, or even your kids' friends, stopping by.
If you avoid opportunities to have company over, then you might have an organizational issue. (Though again, first ask yourself if there are other stressors influencing your feelings.) Not everyone is an extrovert, but everyone should feel comfortable inviting the occasional close companions over without the stress of a massive cleanup.
