John and his girlfriend had been dating for a while now, and he knew her like the back of his hand. He even knew the way that she texted him. This means that if someone else texted him on her phone, he would know it was not her. After leaving her apartment one Friday evening, he received a text that made him feel strange. He could not help but worry about her, so he went back to see if everything was alright.
He used his key to open the door and rushed to her bedroom. He was welcomed by his girlfriend, making out with his close friend. Without his gut feeling, he would’ve never known who she truly was.
