What's the proper grammar for "My and my roommate's home..."
The rule I learned is it should still be grammatically correct after removing the second part. E.g. after removing "and my roommate's", "My home..." is still valid. However, even though I'm a native speaker, "My and my roommate's home..." sounds weird. Is this rule correct?
NB with regards to "My wife and I's seafood collaboration dinner" , that question is only tangentially related, as the rule I've asked about doesn't apply. Nobody says "I's seafood dinner"!
