Options:
— Wallow.
— Celebrate.
— Ignore.
For the first, you can have a few beers or other intoxicants, play some blue-mood music, and think about being lonesome until you feel even worse. You can even go out and do this in public someplace.
For the second, you can really get into the spirit of the holiday all by yourself, watch fireworks on TV, go out to a live display, play patriotic music on the radio or other device, and blow up something minor or get some sparklers going.
For the third, you just make like it’s any other day and do whatever you might have done otherwise: do laundry, watch TV, play with fluther, go for a walk or a ride, burn up some time with a game, read a book, watch a movie.
I’ve done all of the above at one time or another. Each is fun in its own way. Why not try whichever one you haven’t done before?
