You look chilled & maybe scouting for a tea shop? What was your grandson looking at through the slats?
My Grandson likes to pick up tiny bits of sand and put them down the holes. He finds it very entertaining :0)
I think you're 'people watching'!
It's one of my favourite pastimes :0)
You appear to be watching someone doing something questionable to me. That's the scary part of people watching, but the interesting bit too.
I do seem to be frowning a little so maybe it was something questionable :0)
