When it rains, it pours

So, as I said in my last post, I went to the tri-cities. My mom's car was kinda stuttering, or revving. So she took it in, and they said everything was fine. We started driving home, and after about half an hour, the car ran really rough and messages started popping up. We pulled over, and called roadside assistance. They said to turn the car off or we would damage the engine, and they would get a tow truck, but it could only take TWO people, and we had 4 and a dog. On top of all that, the tow truck would come in TWO HOURS!!! Luckily, my dad called the dealership and the guy got a rental car and picked us up and the tow truck towed the empty car. We stayed at the hotel another night, but they still don't know what's wrong with the car! We're driving home in the rental today, and later Mom's going back to get the car, once it's fixed. And we might get caught in a little snow, too! When it rains, it pours! At least I don't have to go to school today...
