just write a majorly long update then your readers(like me) will forgive you for the wait and don't end im not what you expected i love it soooooooooo much
Well if you can't update you can't update! If i were you, I'd leave a note for your readers, and then over the two weeks, work on an EPIICC update, that you can be really proud of, and then post it when you come back. But make sure it round some things off, so that the readers can feel like the update wasn't a filler.
But can I just say, this is a writing site, to do what you want. A few of your readers may get irritated if you don't work on it, but thats there problems not yours. Do it for yourself :)
Well, funnier for you to see your comments getting snippy.
