<human>: So I drive over to my grandpas house to help him pick some olives, grandma tells me he's over at my uncles moving a trailer so I head down the street. As I arrive my grandpa is backing his truck into the side alley where the trailer sits, I drive past him, hop out the car  and chit chat a bit. I feel something bumping my leg, look down and the most adorable black and white puppy is jumping at my leg, I pet him, rub his ears, go aw, the whole works. Grandpa pipes up he's got stuff to do so move out of the way, as I'm walking to my car I notice the dog is running around my grandpas truck tires. I promptly walk over, pick him up, bring him to my car and pull forward about 10 feet. I get out and go to the fence where he came from. I call out and a lady walks out and gets him, we chit chat a few seconds and say goodbye, I turn to go to my car.....

And it's rolling down the alley way

SHIT SHIT SHIT SHIT SHIT

Mind you I'm 310lb so I'm a big guy, I book it down the street sprinting for my car, the door still open, thinking "Okay man don't fuck this up, you hop into the car seat like always, align yourself to the road and put your foot on the break"

*Running*
*Running*
*Running*
*Catches up with car*
"Okay here we go"
*Put my foot the doorway and fall forward immediately into the car seat*

So now at this point I'm basically being dragged along the ground holding for dear life. I know I'm still off center so with my right hand holding my seat I reach up with my left hand, align the car, then reach over and pull up on the emergency break. the car slowly stops and now I'm just sitting there out of breath realizing how fucking stupid and awesome that was. I smashed my left big toe and scraped my right leg a little but overall I'm in good condition. I know better now.

Provide a brief overview of the text.
<bot>: Picked up a puppy and moved my car so my grandpa could get the truck out without running the dog over, forgot to put the breaks on my car and almost ran myself over trying to stop it rolling down hill.
