In Thomas S. Monson's story he talks about his friend, Danny and him, at eight years old of him and his friend wanting to have a camp out. Them being at eight years old were excited to have a camp out, but all they needed to do was clear an area to have the camp out. So they had the idea of ripping out the plants from the ground. As the time passed by their excitement faded so Thomas had an idea. His idea was to burn the plants in a circle to clear the field faster. His friend agreed with his idea, now just thinking about it these boys thought it was okay to play with the matches and light them up. So they did and at first they thought it was working but then they realized that the fire wasn't just going to extinguish its self out. So they did what they thought was best, they called for help, and people were rushing back and forth to get water bags and trying to put the fire out. Now these eight year old  boys thought it was a good idea to play with the matches even though they knew they were not allowed to play with them. This wrong decision caused a very big negative effect, they disobeyed and there was consequences for it.
