MK, and all, I HATE to be a wet blanket, BUT I WILL!
It's my personal experience that when you need help, they are not anywhere to be found, or forgot, or thought you meant next year~my personal favorite, or argue whether it needs to be done at all.
It's when they volunteer helpfulness is the time to make them go away ASAP. (or just say you gotta go pee, by the time you get back they're long gone).
Notice the generic 'they' and 'them', I know 'they' don't take hints or direct orders very well.
Especially the 'red neck' types, of which I am most familiar.
