Playing With Fire
You don’t understand how quickly a fire can spread until you witness it firsthand. If fire catches the wrong material, it’s only a matter of time before an entire fire is spreading across a field or house, with no signs of stopping.
When this internet user was 17, his friend was playing with fire. He ended up setting an entire field up in flames. His dad was incredibly angry and ended up taking money out of his college funds to pay for the damage to the field and the hunting camp lodge, which had burned down. While his friends went off to get degrees, he had to stay at home and work. Sadly, this one mistake had a ripple effect on the rest of his life (via The Brainy Penny).
