Was at a girlfriends place (around 82 when I was 12) in Leidschendam. We where walking next to a canal and we saw a kid on a tricycle. Next thing the kid was gone and we noticed he fell into the water but he couldn't be seen in the murky water. We ran into a backyard calling for help, the kids dad was there and he jumped in the water and resqued his kid. Must all have been in less than a minute.
