Telling you that shuffling round a shopping centre like a little weasel, hiding a video camera in your jacket, and posting videos of strangers on the internet without their consent is all weird behaviour...that IS constructive criticism.

It's pointing out that maybe people are not there just for your consumption. It's pointing out that you don't get to swan through life feeling entitled to using people as you see fit. It's pointing out that maybe there are more mature ways of spending your time...

...all of which is steering you down a path that is more attractive anyway, not that you'll understand that I don't suppose.
