These are the "seasons" we all go through in life... And they are more challenging than any hobby car race, for sure.
So sorry to hear about your mom Jim, and I totally understand (first hand) about the shift in focus away from the car.
Let the car sit, let it get dirty, and every time you glance at it, don't feel any guilt about neglecting it. Just be thankful that it's still sitting there (mine isn't
)
Seasons pass... and when all the family business is settled, and all the bills are paid, and the fog on your brain has cleared; and when you can look at the car and smile about the fact that your mom wanted to to do the things that make you happy, then you will know that it's time to re-aquaint yourself with the lesser-important (but maybe more pleasant
) aspects of life.
All my best regards....
