"It was that exchange, when we finally mentioned the closing of Hailsham, that suddenly brought us close again, and we hugged, quite spontaneously, not so much to comfort one another, but as a way of affirming Hailsham, the fact that it was still there in both our memories."
These two quotes are both from a part in the book where Kathy comes across Laura again (an old Hailsham friend), there is a small exchange between the two before they both realise how much has gone from their lives after Hailsham closed and held onto each other because of this.
