@oristarA,
To show everyone in the known universe.
Because (and I’m being sarcastic/not sarcastic here) it is vitally important that everyone know your opinions and feelings of all and every thing that has ever happened.
Many people feel so strongly about informing complete strangers about their innermost thoughts they plaster their car bumpers, put signs on their lawn and tweet Facebook and use every other method available to grace us with this information.
