Paul,
My answer to your question at the end of your post is YES ... to both parts of it!!!
That ungracious response you received sounds much more polite than some of the things I have seen said by some very rude, inconsiderate, and probably stupid people (is that just as bad of me to throw "stupid" in the mix?).
If you are hurt by the inconsideration of others, that can be described as being "sensitive" ... which, to me, is proof that you're human!
Oh, by the way, I want to thank you for being that way!!!
