Shopping for the future

How the heck am I supposed to know what all we'll need in the new apartment (*crossing fingers that we will get one before the wedding*). Seriously though, there are so many things I could get and put on the registry - yet, will we use it or will it sit in a drawer forever? I did put a mortar and pestle thingy on the registry and I was like Hell yea, I can't wait to make guacamole at home like they do at Rosa Mexicano. Is that a weird thing to say?? I guess I'm growing up and I can't wait to be his wife!
