Do feel the need to announce your presence everywhere you go?
I used to care about my car, I even washed it. After the dents and scrapes started appearing I stopped giving a shit and just got on with my life, saves me money on lotions and potions that I can spend on other stupid shit.
I get the wanting to keep it nice and all that but there does come a point where you realise it makes as much as no difference anyway. Ripped the front bumper off on an errant heras fence the other month, cost me ~30p and 20 minutes of my time (due to darkness) to fix from the multipack of clips I already had.
Back to the OP though, I feel your pain, despite the above it still **** me off when people don’t treat things they don’t own like shit.
