sorry, meant i will reply to kissing - here goes
No, no difficulties with taking things literally, or generalising, or abstracts. I believe those things can be difficult for deaf children who have not been exposed to enough contextual information (e.g. earlier this century/late last century in deaf schools where profoundly deaf children were not allowed to use sign language and therefore had very limited language) - but don't think that is your daughter's situation (especially if she is a prolific and advanced reader which it sounds like she is!)
yes, yes to some people being very hard to hear. For me, it's women with high breathy voices, anyone with an unfamiliar accent, or those people who swallow their words/don't move their lips much. Most children born with a hearing impairment naturally lip-read to some extent, so people with beards or who cover their mouths a lot while talking are difficult too.
Missing parts of a sentence is often a problem. In English some of the crucial contextual words in a sentence are also the short, quick ones which people tend to mumble, which is a problem.
For example:-
DH: 'mhmm to the shop mhhmm get butter.'
That could be:
"I'll go to the shop and get butter'
or 'Can you go to the shop and get butter;
or 'I went to the shop and couldn't get butter'
etc etc.
So, I've heard most of the sentence, but I don't know whether I want to answer 'Okay', or 'No' or 'Oh dear'... Just missing a couple of words means you lose the gist.
The worst thing you as the hearing person could do in that situation if the partially-deaf person says 'What?' is look annoyed and say in a loud, exaggerated voice 'BUTTER! ALRIGHT?'
The look of annoyance creates stress which makes understanding a bit harder. And repeating just one word doesn't help the partially-deaf person get the gist - that's probably the word they already got, anyway. Best thing is just to repeat the sentence in a normal voice, or even better, rephrase it slightly - e.g' 'There wasn't any butter in the corner shop when I popped in.'
My hearing doesn't physically fluctuate, but of course my ability to pay attention does, which has the same effect - so if I'm tired or stressed, my brain won't be able to decipher quite as much. That was more marked in childhood I think (children have less reserves to draw on, perhaps).
