TOUCHA TOUCHA TOUCHA TOUCH MEhardcore fans will criticize the spelling

Looking is optional... and sometimes frowned upon

Walking and texting... can turn a mall pell-mell into a pool

A city street... as it really is

A city street... as we wish it to be

A city street... as we think it might me

If this was a first-person shooter... we'd have a controller
