Birch Bay Craft Observed by Young Girls

I was about 8 years old,my friend and I, the  same age as myself, were staying at  her grandparents summer home in  Birch  Bay, Washington. It  was late evening, everyone was in bed. In my friend's room we were up late talking and giggling,trying not to  wake anyone-or get  in trouble.
I sat up in bed to look out the window. I had this strange feeling. I looked in the yard -nothing. I looked up, and there, to my left, above the trees was a ufo. This was what I remember; the craft was hovering, not too high, at an angle. The side closest to the ocean tilted slightly down. The house itself was three blocks from the  water, and the craft appeared to be just a bit closer than that. It  was  saucer like, fat in the middle, and I remember  thinking how it looked very sleek. The moonlight reflected off the craft, illuminating it's shape. It might even have  been a full moon that night  which inspired me to look out the window.
The  craft had lights (round)  encircling it. They  would seemilngly rotate around the craft, changing colors on the way back around. I remember seeing blue and red, aswell as orange.
I casually told my friend there was a ufo outside, to impress her with my blase  attitude. She didn't believe me at first, but then she saw it. We sat in her bed for a while staring at it. W e  thought about waking her  grandparents, we  joked  about very tiny green men marching in the house if  we didn't  wake them. My friend went to  sleep shortly afterward. I would occasionaly check to make sure the craft was still there:it was reassuring.  The next thing I  remember is  realizing I had fallen asleep. I sat up in bed and looked out the window  again but,the craft was gone.
