I remember this when I was younger. Took a girl I was keen on to a John Mayer concert at the Belvoir Ampitheatre (Amazing venue). I was probably 16/17 and things were starting off well but of course a fellow girl in our year and her boyfriend ran into us and decided to sit right next to us and just ruined the whole night. She wouldn't stop talking!
More of a 'cockblocked by yappy teenager' story than an awkward flirting story
