Today, after Susan had been home for a few hours the daughter said quite casually 'Guess what I saw today.'
Susan indicated through her facial expression that she didn't know.
'I saw (brother's name removed for purposes of privacy) naked' and then erupted into teenaged laughter.
'OMG, front or back?' was Susan's horrified inquiry.
'Back'.
'Thank goodness' said Susan, most relieved.
