My English teacher was saying that English has "evolved" so that saying "Jim and me" or "me and Jim" is acceptable to use in instances like "Me and Jim are going to the bathroom". Here is what I found on http://www.businessinsider.com.au/i-or-me-grammar-mistake-2014-12?r=US&IR=T
Consider these two sentences:
He’s taking Jane and me to the park.
<p>He’s taking Jane and I to the park.</p>Which is correct?
If you said the first, you’re right:
<p>He’s taking Jane and me to the park.</p>It’s right because “Jane and me” are the objects of the sentence (the things being taken) while “he” is the subject (the thing that is taking). After all, “me” is the objective form of the first person pronoun while “I” is the subjective form.
This confuses me because I was always taught that if you are mentioning another person, you always say "that person and I". Could someone help me, thanks. Please upvote if you have the same question :)
