Big Waves

Why is it that the really bad seas usually come at night????? I am sitting in my cabin and it is nearly midnight. Today we were at sea all day and it was not exactly calm, but now I can see the "White Horses" galloping next to my port hole and I am on deck 3, usual waterline is deck 2. Anyway, I had a good diner and therefore I am not feeling seasick, just a like in a roller coaster. I am sure the waves would make for a spectacular picture, however it is pitch black outside except for the ships outside lighting. I do nonetheless have a picture to share with you - Sunset yesterday evening...... regards to everyone, thinking of you.
