When you're happy you don't always have to be laughing and when you're sad you don't have to be crying sometimes it's the opposite. You laugh when you're the most upset.
I'm not a sad person upset the whole time but I seem to be quite emotional.
I had never felt so lonely and so sad in my entire life.
I must confess that my imagination refuses to see any sort of submarine doing anything but suffocating its crew and floundering at sea.
