The first time I've ever seen Harry live was during On The Road Again Tour. So, you're right, I've never been to any of the other 3 tours. That's not because I couldn't afford it. It was simply because my country was never included up until their last tour.
They had 2 shows in my country for the OTRA Tour & I attended both dates in 2015. My concert dates were literally a few days after Zayn decided to leave the tour. I was pretty bummed out to be honest. It was my first time seeing the boys and then that happened. When my tour dates came—On the first day, I was pretty far away from the stage but it was totally fine cause I knew I was going to be closer the next day. I was still grateful that I got to hear them live.
On the second day, I brought a sign that simply said "Harry". His name was written on blue cardboard paper. I didn't really think I was going to get noticed up until Liam and Niall started to read a few signs that were being shown on the big screen.
I was holding up my sign while looking at the big screen at the same time—laughing at Liam & Niall's reactions to the signs they were reading. It was not a few minutes after that my sign was being shown on the big screen. It took me about 2 minutes to process what was going on and then it hit me when Liam said "Harry, you've got a fan over here! Please wave. She's waving that sign for you personally." then Harry said "Hello!" while trying to find me.
It was funny because I was on the right side of the runway and It was like Harry and I were playing hide and seek. He was walking down the runway and was looking to his left—he couldn't find me. He kept looking around. That was up until he stopped and turned around—he was facing me. He smiled so wide, his dimples were deeper than the Pacific Ocean. He waved and turned back around.
(I still have the video on my camera roll after all these years but I don't know how to put it here. So, if anybody knows how please tell me.)
I never really thought I would interact with Harry since there were so many of us but, I'm really glad I did.
