Night Bump while Turning

Yesternight I bumped the car, lightly thank God, while relatively slowly turning right. I bumped into a parked car. It was a considerably soundy bump. It's been a long time (two months exactly) since I last bumped my car.

I'm writing this now so it can be a lesson learnt for me. I was moving off in a side street and about to turn right. I car was coming from the opposite direction. The two mistakes I did were:

1. Turning my lights off!
2. Focusing too much attention on the opposite car approaching while giving less attention to the parked car on my right side.

I thus heard a soundy bumping sound upon my turning to the right. I was unable to notice the car parked at the corner of the road due to my putting the lights off (courtesy to the opposite car approaching) and focusing too much on that approaching car.

Lesson: When turning to the right side always pay attention to any cars parked at the corner of the street. Always keep the lights on at night even if a car is approaching from the opposite direction.
