I would just wish people thought before they acted... because well... someone might or might not have destroyed my cosplay outfit with an uninvited glomp. Other then that... it's MY personal bubble... XD I don't mind a nicely asked hug, and if asked I mostly will give it anyway.
But do the 14 year old kids realise they MIGHT just attract the 'wrong' people? *shudders* I'm old and wise enough to see what intent someone might have, but do they?
It would be fun to see less of these signs this October!
BTW... I've seen them last October as well, but before that I've spotted them in Holland as well... But if you want the real source... it's just a thing from USA... or at least that's where I've seen the first signs! (It's like a virus, nowadays)
On the other hand, I haven't seen them in Belgium or France... AS OF YET!
As annoying as I think they are, some people DO enjoy them... if we walk around eachother... no one gets hurt, right? XD
