Natalie’s son doesn’t have a lot of friends, so when he asked to have one friend sleep over for his birthday she said yes. She called the boy’s mother, who said that he could sleep over their house on one condition. She needed to sleep there as well. She called it a “sleep under”. Natalie thinks that is insane, but her husband doesn’t see what the big deal is. Should she tell her son he can’t have his birthday sleep over? Or should she let this random woman sleep in her house for the night?
