Hello. Folks! As shown in the subject, I have a question regarding the usage of possessive case. Which one of following is a right expression? 1) These are me and my wife's pictures. 2) These are my wife's and my pictures. I have learned from my English totur that in subjective case "My wife and I" is more natural and common than "Me and my wife". So, in same reason, I think "my wife's and my" should be right, but sounds strange....-_- It's so hard to learn English....sigh. As always, thank you very much for your help. Also, I welcome any other comments pointing out errors I've made in this writing. I appreciate that!
