First of all welcome to TAI
. I hope you have a great time sharing/gaining information you have/want.
As suggested by other members please do not bother about the scratches on the bumper. Its nothing major and i am sure your dad would understand.
So as to learning driving you will come across countless situations/scenarios which will test you and make you a good driver. Though i have been driving for around 6 years now, i am still learning everyday!
