I cringe every time I see one of the boys in pics with fans that insist on touching them, putting their arms around them, pulling kissy faces etc. And now someone touched Harry inappropriately when he was performing?! Celebrities are not props to be used in pics/selfies. There is NEVER any kind of implied consent to touch them just because they are in the public eye. They are not our playthings. Being fans doesn’t give us permission to invade their personal space unless they explicitly say it’s okay.
Decent people understand this. Some, however, clearly need lessons in respecting boundaries.
