People have evolved as social animals and this extends to thinking and interacting. We think better when we think socially (in groups) as opposed to thinking alone.

This in part may be why solo reading and annotating improves one's thinking because it is a form of social annotation between the lone annotator and the author. Actual social annotation amongst groups may add additonal power to this method.

I personally annotate alone, though I typically do so in a publicly discoverable fashion within Hypothes.is. While the audience of my annotations may be exceedingly low, there is at least a perceived public for my output. Thus my thinking, though done alone, is accelerated and improved by the potential social context in which it's done. (Hello, dear reader! 🥰) I can artificially take advantage of the social learning effects even if the social circle may mathematically approach the limit of an audience of one (me).

According to the American Kennel Club, The Newfoundland is a massive breed of English working dog, used for pulling nets, carts, and carrying loads. Newfoundlands also make excellent guard dogs. Henry's puppy would look something like this,

but would grow to be a very large dog.

Terrier is a group of breeds, originally bred to hunt vermin. Some examples include the West Highland White Terrier, Cairn Terrier, and Norfolk Terrier.

These dogs were kept not only as companions, but as useful parts of the household: the Terriers to control rats and other vermin, and the Newfoundland (when grown) for protection and labor. Even so, the Newfoundland’s sweet disposition would make for an ideal companion (American Kennel Club).
