A Jack Production
Fifteen-year old Sean is friends with your thirteen-year old son, Parker.
Sean is big into music, and he's very good at it. He sings, plays guitar, plays piano, and one of his favorite activities these days is making music videos. Since Parker is huge into making videos and the software and stuff involved, the two of them have been spending a lot of time together.
While you don't know the details, Sean recently got into some fairly serious trouble, and he was grounded from his computer and phone.
This evening you received a phone call from Sean's father. He's asking if Parker has recently uploaded any videos to Sean's Youtube account.
You hope not, since you didn't know that he had Sean's password, and because he's not supposed to be uploading anything without you okaying it.
When you tell him you don't know, he explains that a new video has appeared there, when Sean was supposed to be restricted from all computer activity. He claims Parker must have uploaded it. It's no problem if Parker did, but if Sean's lying, he's going to be in (more?) serious trouble.
What's your next step?
