I was sitting at the airport waiting for my flight when I noticed a girl a few seats away. She looked just as bored as I was, so I decided to say hello. We started with small talk about flights and delays, but soon we were laughing and sharing travel stories. An hour passed without me realizing it. I kept thinking about asking for her number, but I couldn’t find the right moment. Then her boarding call came. She stood up, smiled, and said goodbye.... I watched her walk toward the gate, feeling happy that I talked to her and a little disappointed that I didn’t take the chance to keep in touch.What went wrong ? What should've i done ?
