Long story short, I was reversing out of a parking spot (very slowly without accelerating btw) and turned my wheel too soon like the dumb dumb I am and scraped the right bumper of the car to the left of me. I immediately panicked but did take a good enough look to see that there was no dent and took off because, as stated before, I suck. I don't know why I did this. I could have left a note since I was leaving my college and had a backpack full of paper and pencils. I feel so shitty and guilty because I know how upset I would be if I were in the other person's shoes. I know there's nothing I can do to make the situation better but all I can do is think about how stupid I was for bumping the car in the first place. I guess I'm just putting this out there to get it off of my chest because I am definitely one of those people who can't sleep at night over these things. I will say that I feel a bit better after writing this
