Next time you find yourself dealing with a (God forbid) difficult person, find peace in the fact that you just have to deal with them for the time being.
But be a kind soul and say a little prayer for them. Because, guess what, they are stuck with their own miserable selves for an whole effing lifetime!!!
And if you are one of those mean, wicked people like yours truly, dealing with them will also help awaken the classroom philosopher in you.
