Please provide a short summary of the essay titled, Screengrabs, from the collection, Intimations.

Screengrabs consists of several short essays exploring a moment of human connection between Smith and a variety of people. Whether it be with her masseuse, her elderly neighbor, a homeless man she sees often, her colleague, a random passerby in the park, or a family friend, Smith recounts these interactions in brief snippets, dwelling only on the moment and connecting each story thematically to the idea of isolation and the pandemic.
