Funny story.
A friend of my sister parked her car in our driveway when I was 13. I went to shoot basketball (goal was in driveway) and moved my moms vehicle as usual to clear the space to play. I completely forgot her car was behind my moms, and smashed into it.
I freaked out, and remembered she had a boyfriend that was a bit of a hot head and they were having issues. I told her I saw a "red truck" pull up and a guy get out. I figured they wouldn't even realize I knew her X boyfriend had a red truck. I then claimed I walked into the backyard and heard a loud smash.
The police were called, and the cop kept saying "the huge dent in the hood of your car looks like it matches the back of that expedition perfectly." But in the end they surmised her boyfriend had hit it with a baseball bat, and went to question him. Of course, he said he'd been home all day.
I told her the truth last year, and I swear to God she screamed at me, told me I ruined her and her BF's relationship, and told me to get the hell away from her. This is 15 f'ing years ago.
Should have just kept my mouth shut. Figured enough time had passed.
