I came across a video of my grandson, three years old, and me in the garden watching a pigeon on the bird table. He complains, sadly, that the pigeon won't say hello to him and I very seriously, dead pan, reassure him that (and I quote) "Well, pigeons don't talk much and they're not particularly sociable as far as humans are concerned." We have some pretty deep conversations... ?
I've got another 'keen'... Ouch!
