Other then the tranny issue your week doesn't sound that bad, look at it this way:
1)You could have been issued the full ticket and have to go to court over it
2)The squirrel probably could have made it had it been trying, however it wanted to die, as the tree it lived in was cutdown and not only did it loose it's home and all it's food, his wife and little baby squirrels moved in with their "Uncle" Jack, so you did him a favor ending his pain AND you also ground up food for a Crow or other such carnivorus animal so in some small way helped to continue the cycle of life
3)Your mother could have called to tell you she was dying of lung cancer from all those years of smoking and not that she was quitting a very hard habit to kick (I know, I smoked for 19yrs)
See your week really wasn't "The worst ever"
