Sighting

I could genuinely give such a long description here despite barely talking to this guy; basically I was at a concert, madness, yesterday (5th June) and this guy was standing nearby and he looked a similar age to me but probably a little older (I’m almost drinking age so they gave me a different colour wristband to show I couldn’t drink but he had a drinking age band) he was a couple of people infront of me and my best guess is he has something wrong with him(which I absolutely don’t mind btw!) or smth because he was trying to get my attention (a respectful amount not stalking or bombarding me) by turning around and giving me a thumbs up and I would do that back, I don’t know exactly what was up with him but when i tried to talk to him briefly he couldn’t properly respond (non verbal?), I am extremely shy so it was difficult for me to speak to him because he was pretty cute imo, he was maybe 5’6-5’8 because he was a little taller than me he was wearing a black hat and sunglasses and I think he was there with parents, this is such a long shot lmao, I was wearing a grey jumper and black cargo pants and was with my dad, please help me find this guy, he was really sweet ^^
