Here is two new role plays. I can play the son or the parent.
Mom is a hooker and and a pothead. After being picked up a 5th time for working the streets she is given 30 days in the county jail. Her 16 year-old son was sent to live with his Uncle who loves to spoil his nephew. When Mom is released she finds she has been booted out of her apartment and after a few days she finds herself renting out an old weather beaten trailer. Now settled she sends for her son. The boy isn't all that excited about going back to live with mom. They weren't getting on well before she went to jail. Moving into and old trailer wasn't very appealing to him either especially after staying with his Uncle who bought him some new clothes, a skateboard and treated him like a prince. [Uncle may be a perv, which the mom is just figuring out]. The scene would start with the uncle having just dropped the boy off.
The son is 16 years-old and has been living with his Mom since his parent's divorce 5 years ago. His relationship with her has deteriorated with each new boyfriend she brought home. Then one day he came home from school to an empty house. She had run away with her new guy. Having nowhere else to go he heads over to his Dad's house. The two have spoken little since the divorce. The dad has become a bit of a heavyweight in the drug trade. His spacious condo is a big difference from the series of apartments him and his Mom have lived in. The dad uses 3 or 4 older teenagers who are a couple years older than the son to run drugs for him. A few of which he uses sexually. The Father and son don't have a bad relationship. They just haven't had much contact since the divorce. The scene would start with the son showing up at his Dad's doorstep.
Or send me your ideas!
