What is the most expensive thing you own?

@SchoolBelle Just in case you have blurred vision. The question asks, MOST EXPENSIVE.

@Unquestioned Nothing wrong with my vision, old man, and it would probably be unfair of me to question your mental capacity.

Having read the range of responses, any normally functioning person would understand the nature of my query.

Or maybe you simply don't understand context.

I hope you have a peaceful day.

@SchoolBelle A very pleasant and peaceful day to you too old woman. :)
