Everyone wants a piece of me!

Hi everyone,
I love helping people and especially in W.A., because we are all on the same wavelength and it helps me, also with my online business. I couldn't have got where I am without you all.
However, I find it amusing that when I tell people (outside of WA) that I work from home doing my online business (I try), and I think to myself; that they will get it in their heads, " okay, she means, she is busy, and will have no time for me", yet they still show up uninvited and take almost all of my working time, or how about the latest visit: "can you please show me how to get from A to B? I have a GPS, but I need you to come with me to show me how to use my GPS..." WhhaaaT??
...or, those phone calls " we need you...no-one else will fill the role..." expecting me to drop everything and who cares about my life, because in their heads, I am not doing anything worthwhile.
The outside world, is encroaching on my precious time...they just don't get it.
Arrrrrrrgh! I feel like Britney Spears song "everyone wants a piece of me!"
These are the times, I wish the movie 'Matrix' was real and I can easily relocate myself somewhere else for some peace of mind. Wouldn't that be wonderful?
They would stay away, if I told them I am at a normal 'brick and mortar' job, but not when I am telling them I have a work at home business, I am guessing what they hear is, "yay! Saane is free, lets go take up her time and drink free coffee!"
It may sound like I am a drama queen and it is only 6am in my part of the world, but I want to know how many of you here, not only have the same problem, but how on earth do you tell people in a polite way to "Leave Me Alone!"?
I do appreciate you all,
Okay, I'm off to try and give my lonely websites some TLC - mamma is back.
Sometimes setting boundaries with friends and family can be hard.
All the best Snazzy
Michael
