There are many questions I have not answered, and I'm still alive. So, no: it doesn't kill me not to answer a question. Sometimes I just don't know the answer. Sometimes I know the answer, but it requires a long, convoluted explanation which I'm not in the mood for writing. Sometimes I know the answer, but think the questioner was just being too lazy to use Google. Sometimes the question is so badly written that my brain crashes, my eyes roll back in their sockets, and I am overwhelmed by existential angst. Sometimes I'm not online and available to answer. Sometime, the answers already provided are good enough.

"I was gratified to be able to answer promptly, and I did. I said I didn't know." Mark Twain

If I don't understand the question, I will usually re ask...)))) If I don't know answer, I won't answer...)))) If I know but not sure I'll say it as my own opinion...))))) Finally, if I know, I will answer, of course!))))))))

What question? Me no you understand. Grim Reaper.
