I know that Karma is a bitch, but this is getting ridiculous

Also, I do not think I deserve all this. Karma always comes back to you, but I did not do anything that would justify all this.
Well, let's start at the beginning. Aaron came back into town late, booooo. Then he had to work the next four days leading up to his birthday and on his birthday. For his birthday dindin the night before his birthday I had made dindin reservations for a bunch of people at Dragonfly at Hotel Zaza. Let's just say it was not what we anticipated it to be. After that the plan was to go to "Rio", which we did but Derrick and I told Aaron "Happy Birthday" in the car, since we did not make it to the club before a little after midnight. No biggie. We took a seat at the table and had a fun night. The place was a little overcrowded, but it was fun. We got home at 3am and Aaron had to be at work at 9am on his Birthday. I brought him "Sprinkles Cupcakes" before I went to go look at the puppies at Amber's house. Later that night I took Aaron out for his birthday dindin, which was delicious!
Wednesday morning, 3.45am. My phone keeps on ringing with a local but to me unknown number, so I do not answer it. 4am. Knocking on the door, repeatedly. Aaron gets up to check who is at the door and comes back laughing to the bedroom. "There has been an incident with your car and we need to come downstairs to check it out.". Huh??? So, here is what we saw.
Yea... So, if anyone could please explain to me how something like THAT can happen if a car is just sitting in a parking lot, please let me know. Also, I have no clue about cars, so preferable act as if I am a three-year old and explain it to me. Thank you.
My vehicle of choice now is my bike, LOL.
