Maybe they showed up on the stoop one rainy night. Maybe you adopted them. Maybe they talked their way in and wouldn't leave. Maybe you stole them from another family member. Maybe you stole them from a stranger. Maybe you just woke up one morning and they were there.
Hell maybe you had them all on purpose, with a loving partner.
None of that really matters. The fact is that the kids live with you now, and you have to stop doing crimes.
