Number one. Black Friday is stupid.
Number two. Never work retail unless you're home for a year from college trying to make some money and then NEVER DO IT AGAIN. Stay in school kids.
Number three. Don't stay out late with your boyfriend and his family the night before working Black Friday the next morning.
Number four. Try to remember in times of stress that, all in all, the things you do are most likely going to lead you towards a fairly happy and fulfilling life. Try not to get wrapped up in the little things.
And finally, Number five. Kittens are nature's way of making you stop freaking out so you can pause and say "D'awwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww"
Moral of this story is...Kittens make everything better.
