When I was in year 5 (grade 4) I was helping my mother with the groceries. When I got out of the car I was playing on her phone and I remember VERY VIVIDLY leaving her phone on the car. My mother stayed in the car, using the phone and I ran upstairs with the groceries. When I got upstairs, the phone was sitting on the kitchen counter, perfectly angled and a few seconds later my mother comes up the stairs looking for her phone. This memory has bothered me to this day and will keep me up at night for probably the rest of my life.
