Ryan and his friend Lucas decided to go hiking in the mountains. The weather was sunny, and they felt confident. However, halfway through the trail, they realized they had taken the wrong path. Their map didn’t match the signs they were seeing. Feeling worried, they checked their GPS but had no signal. After thinking for a moment, Lucas suggested following the river downhill. Luckily, after walking for an hour, they reached a familiar road. “That was close,” Ryan said. They promised always to check the trail carefully next time.
