e.g. just picking something random: https://inspiringcity.files.wordpress.com/2015/08/wp_2015083... and coming up with something
"The ethereal skeletal-form the character hewn - nay assembled - out of cubic masses I think really suggests a genuine fragility or frailty of humanity in a context of our modern society - you know what I mean, raising questions about the concept of self in an anonymous and increasingly digitised world. The fact this faceless figure is stationary and notably rooted solid here on the spot despite being surrounded by this busy streetscape only reminds me of our ultimate mortality, and that our place - our mark we leave - in the universe is merely fleeting... the artist really hammered this point home I think by the use of rusting steel: nothing is permanent, dust to dust ashes to ashes and all that. Moving stuff."
It is fun - bonus points for ending the critique with "Ultimately, it is about mans's inhumanity to man" for every piece :-)
I like to think that I've been able to get away with it loads of times now ("gee - I just thought it was a rusty metal man statue"). My wife now rolls my eyes whenever I do it with friends, but she lets me have my fun :)
