Would 'I and she' not be more natural in polish?
"Jemy jabłka" or "Jemy jabłka razem" would me natural.
Hm, do we use "ja" here to refer to I because it's happening in the present? In other sentences we use "mnie" and I'm trying to figure out the difference.
It's just part of the subject "She and I", as "She" is in Nominative, then "I" need to be in Nominative as well.
jedzemy jabłka ?
I've just googled this word and it appears to be a not that uncommon misspelling of "jedziemy" = we are driving/we are going by car/train.
