HS graduation, I heard sirens at my house and later learned that a girl from our HS was killed in an accident (someone else ran a stop sign and hit the car she was a passenger in). My oldest was graduating then and graduation was a somber affair, understandably.
My graduating senior daughter was just driving home from the store. I had to check her location and was relieved to see she was still moving in her car. She saw the fire trucks go by.
Got emotional reliving that memory...
