Lost And Found: The Story Of Derinkuyu's Underground Metropolis

He tried to manipulate his mom by threatening that he will go live with his dad. His mom packed his bags and called a cab for him.
A 15-year-old won't be spending a picturesque Christmas because of his attitude over a mistaken McDonald's order. OP's parents have been divorced since he was nine years old.
His mom has primary custody of him because his dad has been struggling financially for years. It wasn't a walk in the park for his mom either, but their life improved once his mom graduated from college.
Their life drastically changed once his mom married Alexander, OP's new stepdad. OP and his mom moved in with Alexander, who is well-off.
In contrast, OP's dad lives with a roommate. They live in a small apartment and share a bunk bed.
OP visits his dad every Saturday. He doesn't spend the night at his dad's apartment to avoid sleeping on their couch.
A tantrum he threw over a burger made OP extremely familiar with his dad's living situation. His mom went to McDonald's and bought dinner for them.
OP got upset when he saw that his burger had cheese in it. His mom knew how much he hated cheese on his burgers.
His mom said that she ordered the burger the way he liked it but forgot to double-check before she left. In response, OP grabbed his mom's salad and threw it all over the kitchen floor.
I can only imagine OP's mom and stepdad were upset when he threw the salad all over the floor. Our opinion of him didn't improve when he revealed that he frequently threatened to leave their house when he didn't get what he wanted.
OP needed to learn the lesson his mom was teaching him. He will come home remorseful or even more standoffish after his elected stay at his dad's apartment.
