Explain the myth of Lilith?

Lilith, female figure of Jewish folklore, sometimes depicted as Adam's demonic first wife.  There was a cult associated with Lilith that  survived among some Jews as late as the 7th century CE. The evil she threatened, especially against children and women in childbirth, was said to be counteracted by the wearing of an amulet bearing the names of certain angels.

Explanation:

I am sorry if I get this answer wrong .I don't know if you are talking about jewish folkore or something else .

the narrator is saying that the old lady made her feel uncomfortable. you know this because they say "i found that rather irksome", "perhaps it was her being so upright and trim", and "i don't think it was that, because i thought that quaintly pleasant." hope this !
