I truly believe that the best way to benefit humanity is to make faces in the bus--slightly mad faces, or puttings out of the tongue suddenly at the person opposite. Think of the thrill that gives to countless uneventful lives to whom nothing ever happens. They can tell everyone for weeks that they saw a mad woman on the bus, and they can exaggerate this to almost any extent. This form of charity can be practiced on the way to work.
Caryll Houselander in a letter to Archie Campbell-Murdoch
Of course, nobody but my husband sees me on the way to work, and he might not find it very pleasant.
It reminds me a little bit of the fat girl in the doctor's office in Flannery O'Connor's Revelation, except that she wasn't so entertaining. Revelation is a bit more painful.
