cars come n go but people never come back....wat u think is incorrect about u n ur dads relationship...its wat i thought too about 15 years back...i can claim this coz wat u did last night was exactly wat i did twice...once in 1996 and once in 2002...first time was completely my fault...2nd time wasnt completely mine but the speed factor was there... i was driving too fast both times....the lesson i learnt then was that if u dont gotta go at 140 then u dont go at 140...thats that. n bauhaut aag lagi howi hay speed laganee hee hay then get a passport n visa n go to germany...drive on the autobauhn.
As for repairs...neither will u be paying nor will u realize wat u have done until the day u buy ur own zero meter car from ur own earned money (own earned is totally necesary) then set it up with stuff of ur liking...rims tires...engine mods if u want etc....and then when that car suffers its first damage(major or minor) thats the day...that u will actually be able to feel how ur dad feels right now...till then u only THINK u know how he feels but u actually dont.
Most of us have been thru these stages in life and they come for everyone so dont think ur any exception...breaking ur laptop or other erratic behaviour wont solve the problem...wont bring back ur AMG or ur dads trust. Only way to do that is to fiz things slowly...if ur a student then get grades which wud land u a REALLY good career or a scholarship ahead...this is just a suggestion n it works for many grounded people i have seen
