Do you always have to put other people before yourself?
When you are telling a story about yourself and another person, it is correct to reference the other person first. For example,
Tim and I went shopping.
Given that rule, then is this also the case in the following type of sentence, where you’re forming a possessive of two people, one of whom is you yourself:
Please see attached Paul's and my ideas on this subject.
This doesn't look at all right to me, but aside from rearranging the whole sentence I can't see how to make it right. Can I write:
Please see attached myself/my/mine and Paul's ideas on this subject.
or does that go against the whole rule about putting the other person first?
I know I can make the sentence work by changing it around but I would like to know if there is a rule for this type of sentence.
