Haha my friend did that to me! She said I wasn't allowed to call LO ethan because she plans on calling her son that when she eventually has one! If her and her OH were TTC I wouldn't have minded as much, but she (like me) is 21 and kids are not in her immediate future, so it was pointless, and I told her that... I said ok, fair enough, but you'll probably change your mind when you actually have kids, she changes her mind all the time about names that she likes!
Incidentally I didn't "steal" her name...
