Rules For Bloggers #1:
Don’t apologize for not posting in a while.
Unless you have 500+ subscribers to your blog, very likely no one cares and nothing is more sad than someone saying they are sorry to the Internet. And if you have more than 500 subscribers to your blog, you have far better things to write about than apologizing for not writing.
If you feel you must mention your absence, embellish a story. Perhaps after a night of heavy drinking you awoke to find yourself in the desert in Tunisia with nothing but the clothes on your back. Describe how you used your time honed skills at charades to convince a group of traveling spice merchants to bring you to Morocco where you picked up a job teaching surfing lessons in order to earn enough money for a ferry ride to Italy. In Italy you worked your way up the coast picking tomatoes, fell in love with a beautiful woman whom you rescued from an arranged marriage to an evil Olive Oil Baron, etc.
