But it was just a few minutes!
Ah kids, they're awesome aren't they? Kids and paint are an especially amazing combination, especially when left unattended.
I remember one time when my daughter and my nephew were playing in my basement one day, they were probably about 3 years old at the time and my sister and I went upstairs to get a coffee. When we returned just a few minutes later it was like that final scene from The Blair Witch Project where the campers see all the various tiny hand prints all over the wall of the creepy cottage. Only instead of various hand prints it was just two sets of hand prints, and instead of a creepy cottage wall it was my basement wall, and floor, and coffee table and anything else they could reach in a matter of 5 minutes.
Fortunately for me it was washable paint and my basement was unfinished, but it was definitely a teachable moment for me about how long you can leave a child who has access to paint unattended.
I think this dad, who recently filmed the aftermath of leaving his own kids alone with paint, has learned the same lesson.
