Yes.
When I was around 11, my parents felt bad for this homeless dude who knocked on our door begging for cigarette money...and let him live in our living room.
It went on for a month, and he never did anything except watch TV, make a mess, eat our food and harass our neighbors. I complained to my parents, but they just called me selfish.
Of course they let him be in the house alone with me while they were at work, and I caught him KICKING OUR DOG.
That did not fly with me, so I flipped out and threw things at him and literally chased him out the house. He made himself scarce in a hurry.
When my parents got home, I told them he decided to move out on his own, and he tripped over our dog on the way out (so they'd check her for injuries).
I never told them what really happened until I was 20. And of course they were horrified and were upset that I didn't convince them more to kick him out.
I really wish I was making this up.
