What do the swans symbolize in “the wild swans at coole”?

 The swans are a symbol of beauty, but also of energy and permanence. They don't seem to age the way the speaker does, and they aren't conscious of pain and weariness in the way that the speaker is. Although the swans impress the speaker greatly, they also remind him of the pains of getting old and the inevitability of death.

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 !
