I have a lot of other feelings/emotions, particularly about how the driver behaved (attempted to leave the scene, repeatedly screamed at Sam, called him (and the other witnesses) a liar, tried to get Sam to talk to her insurance company to admit fault, etc), but instead I will focus on the witness who spent 90 minutes of his morning with Sam, shielding him from this person, getting a hold of my husband, calling the police, and being Sam's advocate. He also followed up yesterday to check on him. Super, super grateful that we had someone to help us out.
All of the feelings. So incredibly grateful that Sam is okay.
