There's no other way to say this:

I'm sorry.
And I'm even more sorry, but in approximately4.5 minutes my laptop battery is going to die so I must also make this apology quick.
I consider blogging to be very important. As important as taking a shower every day! And so I apologize for stinking!
Lately... I can't even use the excuse that I've been busy because I have not been any such thing! I would like to promise you that it will get better. If I've disappointed you... Please don't leave me!
The blogging will continue!
