First up: The widespread use of “…and I”, especially as a way to end a sentence! How exciting.
It is really quite rare that “…and I” is the correct way to end a sentence. This is because “I” is the subject pronoun, while “me” is the object pronoun. But what does this mean, you ask? (And if you didn’t, you probably should be asking tbh.)
The only acceptable scenario in which to end a sentence with “…and I” (as in, “my boyfriend and I”, etc) is if it would be possible to continue the sentence with for example “are going” or are performing some other form of action. And even then, it’s pretty sloppy sentence construction if you ask me. If you can’t do this, then it should definitely be “me” and not “I”. Ie., “Tom received that present from my boyfriend and me”.
Another way to remember this is that if “…and I” could be replaced with “us”, then it’s “me” you’ll want to use. If “…and I” could be replaced with “we”, then “I” is the right choice. And I’m sure you’ll agree that “we” is an odd word to finish a sentence.
Of course, “…and I” is used mid-sentence as well. In this case, there is definitely a better shot of being correct if you use the subject pronoun “I”. For example: “My boyfriend and I are going to the park”, ie. it could be replaced with “We are going to the park”. However, an incorrect use of this mid-sentence would be “Tom is taking Mary and I to the park”. Tom is the subject in this sentence, and “Mary and I” forms the object and could thus be replaced with “us”. Therefore it should be “Mary and me”.
In conclusion: Ending a sentence, or replacing “me”, with the subject pronoun “I” is not clever and fancy, it’s sloppy at best and in most cases completely incorrect and makes you sound like a pretentious twat.
