You thought my essay assumed the reader knew something already, which means that my English is too poor.

"It's easy to get distracted at a party, but there is always someone who will notice other people's empty glasses and fill them for you." should be fine then.

I’m not sure if you see what I mean.
Especially, I don’t understand why you wrote the last part “for you”. I don’t see what you imagine about a Japanese party.
“For you” sounds like the people fill other people’s glasses for the readers(who is reading this essay).
Usually, all the Japanese people at a party try to pour for other people. So, if you are too out of focus( Is this expression correct here?), you can’t have any chance to pour for anyone.

Or even when the receiver and the giver are both you; 'I poured for myself' but we don't say phrases like that too often, especially for actions your normally do by yourself anyway,

“Especially for actions your normally do by yourself anyway”
I don’t see what you mean.
Young women normally don’t pour by herself here.

“I poured for myself” is odd. OK.
So what can I say?

I think maybe it's similar to the difference between 自分自身のために and 自分で。Like, maybe you 自分で朝ご飯を作った、but it would sound weird if someone said 自分自身のために朝ご飯を作った

I’m so sorry, but I still don’t understand.
What do you say this in English?
『自分で自分のグラスにビールを注ぐ』

Japanese young women can’t 『自分で自分のグラスにビールを注ぐ』.
They have to wait someone notice and pour for her.

Please tell me.
Thanks a lot!!!
