At ease (Williams)

They were both very shy, and they knew each other slowly, tentatively; they came close and drew apart, they touched and withdrew, neither wishing to impose upon the other more than might be welcomed. Day by day the layers of reserve that protected them dropped away, so that at last they were like many who are extraordinarily shy, each open to the other, unprotected, perfectly and unselfconsciously at ease.

John Williams, Stoner
