Jenn, I have been where you are, got the looks and the questions, and decided to use the question and answer period as a teaching opportunity. That sounds harder than it is. You have a story to tell, go ahead and tell it. If you save just ONE person from having to go through the cancer and its after effects, it's sure worth it.
I also pointed the ones I thought were truly interested (and not just making lip noises) to the OCF site for more info. I have seen five of them on the site already, so maybe it's done some good.
