Suppose I want to refer to the widget owned by me and Susan.
Then do I say "you are welcome to use Susan's and my widget"? (Sounds awkward.)
Or "you are welcome to use the widget owned by Susan and I"? (Too long, clunky.)
How do I say this correctly? I would prefer not to rearrange the phrase altogether to avoid the problem. How do I correctly format the possessive with the multiple parties?
