Baby shower rant

My mom asked me to write out the invitations and I did. On them I wrote were I was registered too. My mom gave some to some "friends" at her job and they started talking saying "omg they put where to buy the gifts." I feel horrible and emotional. Was I not suppose to do that? I feel like crying and so embarrassed. How else were they suppose to know where I was registered at? I feel sad, this is my first time doing this.
