person A: I promised my sister that I would go sky diving with her when she was old enough to_comma_ but I didn't think she's remember. I'm horribly afraid of heights.
person B: How long ago was it?
person A: I promised her about 8 years ago.  I was much younger also but now I have two kids and don't really want to do it.  Thinking about dying or even just jumping off a ladder_comma_ much less a plane_comma_ seems awful!
person B: Maybe you can talk to her about it?
