Got any great pics of your pets? Today's the day to post them and et us see who you hang out with.
It's also National Cheer Up The Lonely Day. Mark Twain wrote "a burden shared is a burden halved". If you know someone who is alone a lot of the time, make a call, send an e-mail or text or tweet or whatever. It's easy to cheer someone up.
Sending a pic of you and your pet might be one way to do this.
Enjoy.
