I'm reading The Paying Guests by Sarah Waters and I don't understand what a "hard society woman" is in the following paragraph:
'Did you ever kiss a woman before? Did you ever hear of such a thing, before you met me?'
Lilian was blushing, still stroking, following her fingers with her gaze. ‘I don’t know. Yes, I suppose so. But as something indecent. Or as something a hard society woman might do; not as something real.
By "such a thing", she means two women falling in love. Is "society woman" a upper-class woman? If so, what is a "hard" society woman? And why is it something only a hard society woman might do? Can anybody explain the idea for me?
