Oh dear - I think that is how I always do it For the most part - I do NOT like my part of the converstaion repeated and so I generally delete everything on my reply before I type - but when it is something I am responding to - I leave the other person's part first.

I know when I am having a longer conversation - I like to go back and re-read what I wrote before I read a long reply, to refresh what it is they are saying. Mostly I save my e-mails for awhile so I can do this -- but Yes, I do leave the other part I am replying to at the top
