Unless you are embarking on some kind of Oral Cancer awareness project, why bother with them? Tell who you need to tell and that's it. Just so you know, those are not all off the wall questions, it is just what pops into peoples minds. Depending on your assessment, or their assessment of the relationship, a question can be appropriate or inappropriate. I have had the will question thrown at me and I know it is out of concern for my teenage daughter. After the initail shock, I get it. Inappropriate, no. A bit of a shock, yes.
