You throw a party or host an event and you go to great pains to ensure its success.  Can you truly guarantee that all will enjoy it, that they will be happy?  Of course not.  The only thing you can control is your mind.  Watch your thoughts at your event—every moment of this party you call Life.  Be present and flow.  Do all you do with the intention of being the Light.  You need do nothing other than be present and shine.  Whether others put on their sunscreen is their choice.  They may choose rose colored glasses or reflective glasses that completely block the Light—it is no reflection on you.  Do your best and flow with higher guidance.  That is all you need ever ask of yourself.
