Crashed the family car on my first day driving. Into our house. Our driveway is a mini hill with a turn to get in and then loop to the side with the corner of the house being at the corner. Accelerating up the little hill meant the house jumped in front of the car! As it was my first time driving, the blame was placed. Firmly on dad, as teacher.
Luckily the damage wasn’t too bad to repair, but still the two most expensive things were broken on one day.
