Mazbeth,
I think it was the "mere 50'' which sounded lighthearted, if as we both assume, she is female, and continuing the lightheatedness - see also her mention of ''hoping'' re ''boys from Dennis Rd'' - then she may not be 50, and could therefore be ''sweet 60'', as no one has heard of refrains of ''sweet 50'', and ''sweet 16'' is hardly appropriate. Also, women are generally thought of as being less willing to mention their real age, though let us be clear Mazbeth, I'm not accusing her, or you of lying.
When both sexes are much younger than you are now, women are generally more emotionally mature than men - I've often seen a woman of say 26 who was as mature as a man of 30 -1.
