I just had this arousing moment at the train. A HB8 got on the train with her guy. We were sitting opposite of each other 25 feet between us. She eyed me up while her guy was resting his head against her shoulder with his eyes closed. Then she took his head in her hand and started making out with him. After two min she stopped and he closed his eyes again and she went back to staring at me without breaking eye contact once. She did the whole thing one more time and then got off the train alone. Should I have gone after her or is that too risky? Now that I'm writing this I realize the answer is 99% going to be I'm a dumbass and should have gotten off the train with her and given her my number, or asked for hers. Should I have said to call me when she's done with him? Or how could I have given her the chance to keep face and not admit to her hypergamy?
