"Thinking is the greatest torture in the world for some people."~unknown
I must say this is very true, no matter how sad it is. Thinking in itself can be it's own prison, some sort of solitary confinement. It can consume you, keep you up late into the night, giving you the worst insomnia. So, just as a little word of advice, tonight, don't let it keep you up. Save the thinking for a time when you have good things to think about, not endless worries and sad memories while you are alone. Maybe at least one person will sleep a little better.
