thats so u know deep ...... an acted out analogy of your life ahead
...Me again. I cannot recall how old I was, 20-30's maybe, but if anyone here ever saw a person *walking* down the Blackwall Tunnel (London), about 20 Years ago, while dressed in Smart Clothes, then that was ME, okay? This counts towards what others have said here -- it was weird and uncertain - yet GREAT when I succeeded in doing it & came out the other end!
I used to go into Manchester and lie down on the street for hours waiting for people to talk to me.
Greetings. This is England; so many Folk would be polite and ask You if You 'are alright', or ignore You... yet their Children would approach You and do other things which I do not care to mention. (...!) Also, a lot depends upon Your eyes being open/closed, or Your showing any 'signs of life' (twitching, moving, etc.) ...!
I Myself once genuinely tripped over at school & after the pain I saw opportunity to try a similar experiment. Most onlookers (children) gathered to say mean & imaginary things, and only a Friend arrived to help Me up. Yet the entire affair was ended when a Teacher arrived, to *force* Me up (ignoring My leg pain) just to disperse the crowd. (!)
I think nowadays most folk would do either of THREE things: Ignore, offer to remove You out of the Public Area, or just take Pictures upon a Smartphone. (Meh.)
...If lying upon a street deliberately waiting, then most folk would notice that and avoid it, thinking it suspicious - as if You were a "caught on hidden camera" sort of Actor.
I list many perspectives here, so I hope this post is at least a bit useful. (To anyone else also.)
