Erin,
Accidents happen...sometimes all too easily. That's why we have insurance.
I'm sure that your Dad didn't do it intentionally. Its not as though he was speeding recklessly down the highway saying, "Lets see what this baby will do."

It might be better to extend some undersatanding and forgiveness in his direction. Even if it is only to ask him if he is OK.

Scratches in sheet metal can be repaired and remember, cars have no feelings.
Damage done to relationships, are not so easily repaired...the scrapes and dents seem to go deeper than outward appearances.

With love, Erika
