Hey, just remember that life is too short to always be angry, be bitchy, be egotistical, to be anything but kind.
Just when you aren't prepared for it, someone will put you in your place and you won't like it.
God will take a loved one, and you won't be expecting it.
You'll feel sorry and regretful. Just avoid that and call, write, send a text to those that matter and those that you love. Most importantly, tell your parents or whoever raised you that you love them and truly appreciate all that they've done for you - because they're the ones that dealt with your shit for 18 years [at least] and still haven't beaten the shit out of you (even if you truly deserved it).
Peace, Love, and Happiness
