OBJECT RESEMBLING STAR MOVED IN TRIANGULAR PATTERN THEN VANISHED

TIME AND DATE ARE NOT EXACT. A FRIEND NAMED TONY AND I WENT OUTSIDE TO GET SOME FRESH AIR AT A PARTY. aLCHOL WAS INVOLVED BUT NOT A FACTOR.  WE LEANED AGAINST A CAR AND BEGAN LOOKING AT THE STARS WHEN WE BOTH NOTICED A STAR MOVE.  tHE STAR LOOKED LIKE ANY OTHER STAR EXCEPT IT WOULD FLASH RED MOVE FLASH BLUE AND STOP.  I COULD BE WRONG ABOUT IT FLASHING RED AND MOVING AND FLASHING BLUE AND STOPPING IT COULD HAVE BEEN THE OPPOSITE IT WAS ALONG TIME AGO.  tHE OBJECT MOVED IN A TRIANGULAR PATTERN.  wE OBSERVED THIS FOR TEN TO FIFTEEN MINUTES.  WE CONCLUDEDED IT TO BE A UFO.  I SAID WE HAVE TO GET EVERYONE OUT HERE TO SEE THIS OR THEY WILL NOT BELIEVE US.  i RAN INSIDE AND AFTER A MINUTE OF TRYING TO CONVINCE EVERYONE THAT THEY NEEDED TO SEE THIS WE ALL HEADED OUT.  WHEN I GOT OUTSIDE MY FRIEND TONY SAID ITS GONE I SAID WHAT DO YOU MEAN GONE HE REPLIED ITS GONE VANISHED .  OF COURSE NO ONE BELIEVED US.  THE OBJECT WAS IN THE MIDDLE OF THE SKY AND COULD NOT HAVE GONE OUT OF LINE OF SIGHT. AND TONY WAS INSTRUCTED TO NOT LOOSE SIGHT OF IT.  HE LATER TOLD ME IT WAS THERE AND THEN IT SIMPLY VANISHED.
