<human>: Last Saturday, at around 10:30pm, I was lucky enough to go out with my parents and buy a car. I was pretty excited about this, since I passed my test months ago but didn't think I'd have a car any time soon, due to lack of funding. So we bought the car, drove it home, enjoyed the freedom of traveling to places without the limitations of bus routes or walking. Everything was pretty sweet and I couldn't wait to show it to my friends at sixth form on Monday.

This morning, I fucked up. I was running late. I quickly packed my stuff, chucked it in the boot and was ready to leave in my shiny, second hand car. As I was reversing out of my awkward driveway, I was doing my best to avoid a hedge. While focusing on one side of the car, I'd completely blanked the other side and didn't see where my mum's car was parked. As I hastily reverse, I am suddenly startled by a loud "CLUNK!" Shortly followed by the sound of scraping metal against metal. Stupidly, I panic and don't stop reversing. All that I'm thinking is "FUCK. FUCK. FUCK. FUCK" as I watch my car pushing my mum's car across our gravel driveway. As this continued, the wing mirror of my car fell off, I stalled the engine and remove myself from my car, petrified. 

My mum comes out of the house, screaming "What the hell was that?! Are you alright?!" She quickly realizes what has happened. She doesn't yell at me, instead she just seemed disappointed, looked up and asked me "Shit, Ben. What have you done?" 

We take a moment to assess the damage. The corner of her rear bumper is completely caved in. My wing mirror is snapped off, and to top it off, I have a large dent and scratch mark all the way along the side of my car.

We taped up the mirror quickly and I arrived at school 15 minutes late... After doing a U-turn half-way because I forgot I had told my girlfriend that I'd give her a lift.

Provide a brief overview of the text.
