‘Do you suppose Miss Bates... «Jane and Prudence»

‘Do you suppose Miss Bates has any love life?’ asked Marilyn idly one morning after Prudence had been staying with Jane. ‘She’s quite attractive still, really.’
‘I wonder how old she is,’ said Gloria. ‘About thirty, do you think?’
‘Oh, yes, must be. I hope I die before I’m thirty – it sounds so old.’
