I had a date with a girl I’d been chatting to online for years, but we had decided to take things beyond friends. She got a flight to see me (US to UK). We thought it would be fun to not share any photos beforehand. However, just after she arrived in the UK, she started panicking and wanted to see a photo of me. I obliged, in order to ease her nerves, and she freaked out, booked a flight back the next day, avoided me and flew back out.
So my worst date was a no-show in the worst way possible.
