WM,I am sorry you crashed and you are right, it is not the end of the world, nobody got hurt and the vehicles are repairable.
Keeping this to yourself is a fine decision as we don't have to go looking for anxiety and if you know your Mother well, which I am sure you do, you do not need any quilt laid on your shoulders. You had an accident, and thankfully all is OK in your world.
Blessings,
Kitt
