An amusing anecdote :-)

After she had married and come to live at Overstrand Mansions, Annie [Firmin] recalled an evening when Chesterton came round to their flat on his way to dinner at the House of Commons with a shoe on one foot and a slipper on the other. Did it matter? Chesterton asked, when it was pointed out to him. 'I told him I was sure Frances would not like him to go out like that- the only argument to affect him'
