I can't explain why exactly, but I'm very tense at the moment. I think it's a combination of factors:
a) a lack of sleep (which was caused by)
b) a frightful dream I had last night (pertaining to)
c) a person that I hold dear to me (who intentionally or not, is causing)
d) a lack of communication
Any or all of these could be the answer, or it could just be that I have a very important meeting tonight with a person of high rank.
Hmmm... which one is it....
