I personally enjoy real life real time watching people walk into fountains and planters along a street. Seen that numerous times. Maybe I can be a jerk at times but when I see someone walking towards me or even close by and have taken many steps without looking up, when they're close enough I shout loudly "LOOK OUT". The startled jumped reaction is precious.
Only have a few got mad at me but I just walk away. Too many times over the years I've done it for real to save their bodies and face.
Used to be able to tell who was talking out loud to themselves, crazy or not.
Now so many are talking fewer are exchanging smiles. Still manage to catch a good number while in walk time and it's warming when you do. For all involved.
