(From A Terrible Kindness by Jo Browning Wroe, Part I, Aberfan, chapter 11)
The pavement fill with black-clad figures oozing from doorways. Keep your head down and your heart hard. That's your kindness. Earlier, gazing into the purple dawn through the widow-screen, William imagined a cup of tea with Betty, hearing about life with her sister-in -law. Now, he tells himself, he mustn't think like that; he should leave these people alone, drawn tight into the folds of their community.
I take "drawn tight into" to mean "integrated tight into", right? However, "drawn tight into" seems to emphasise the mutual bonding in the community.
