>>52152237You sound ESL, so I guess a prestige course for what you didn't learn in school is in order here:
English is a language with alternating levels of stress on different words. 'All' is a softly-stressed while 'I' is a hard syllabant.
(This is always why Japanese speaking English tend to mispronounce it so badly. If your meter is off, even if it's not wrong grammatically, it sounds incredibly weird. There's a character in Half-Life called G-man that deliberately misstresses words to sound inhuman and weird if you want to see this desynchronization at an extreme.) 'I love you' has a hard-soft-hard metric flow while 'all of you' is soft-hard-soft... and it's obvious to any native speaker without either hearing impediments or autism that she's using the first. Also, there's no reason for her to pause and lower her tone for an 'empty' phrase like 'all of you' which didn't require either emotional investment or logical processing. Again, English was a language tailored around a sing-song rhythm, so you have to consider negative space and pauses. Final thing to consider is context; her sentence following this is 'Show love to the other girls' which is kind of a nonsequitur from aforesaid 'empty' phrase whereas it fits perfectly with the preceding sentence being 'I love you'. So, not to belittle you; what you studied academically was a good start and did pay off since you seem able to process basic ideas, but you have to consider 'how' Anglophones talk as well or you'll make misassumptions.
So, conclusion: Moom loves us. QED.
