Say you're in a relationship, you go to dinner, things seem to be okay, you take a bite of your food, it tastes delicious so you comment on it to your SO. They reply, being totally serious, with, "I don't want to hear your comments right now." Things just get worse from there but you're trying not to make a scene because you're out at a restaurant. The meal ends, as you're walking out to your car your SO just goes off and starts yelling, you start yelling, they say they're not getting in the car, that they'll walk home. You try for thirty minutes to get them to get into the damn car and they just refuse and seem adamant to walk home. Even though home is a 20 minute drive, it's dark and 40F out.
Do you leave them? Do you drive home and let them find a way home themselves? Or do you stay with them?
Edit to add that they don't have a cell phone on them.
Inspired by this happening to my best friend tonight and he didn't know what to do.
