That's the only bad thing about taking a vacation. When you get back, you still have all of the work you left behind, plus all of the stuff you would have normally done while you were gone. Nobody takes care of any of that stuff, so it's all up to you to handle.

I usually end up doing a "working vacation" where I check email and handle customer requests for an hour or so a day, and then at least I don't have that facing me when I get back.

I hope you get caught up quickly, and can dive back in soon.
