I mentioned this in my concert report but I guess I could go into further detail.
So there were these three guys (early twenties?) standing right in front of me. I noticed before the concert that two of them had written “Oops” in one palm and “Hi” in the other. They were in the front row so when the boys were standing over at our side they would definitely see it. I remember thinking before the show started that I really wanted to see Harry and Louis’ reaction to it so I was kind of paying attention.
One had painted “I love Harry” on his forehead, the other one had “Rock me Louis” (I sneaked a photo of him after the show lol)
These guys were holding up their palms a lot. If Harry saw it and had a reaction to it I missed it because I wasn’t paying attention at the time
Louis’ reaction however I was able to witness.
They weren’t as obvious about flashing their palms in the beginning of the show but sometime after the wardrobe change they were being really persistent like so:
Louis came over to our side of the stage and he was looking directly at them, I’m 100% sure he saw the “Oops/Hi” written in their palms. I hate myself for not recording at the time but I got a couple of pictures
His face when he was standing right in front of us, looking directly at them. I remember him looking a little baffled but he did give them a little smile and it was undoubtedly a positive reaction.
So my point is pretty much that I got to personally witness Louis not being bothered by someone holding up a H/L related sign.
And here is another similar example from a couple of days ago.
