Can you give your comments on this poem 'Sonnet' by Christina Rossetti? Sorry i need it for my homework.Thanks

She's saying that she wishes she could remember the exact day, time, etc. of meeting the person she's speaking to. She's forgotten if it was a Monday, Tuesday, what the date was, etc., yet it sounds as if she remembers very well how she felt that day. Perhaps her feelings of that day are all she needs to remember.
