I'm with Sandie. Asking for help moving a coffee table is one thing. Using your internet is a totally different thing. If you don't trust her, say no. How do you know WHAT she's going to use the internet for??? Wouldn't you be embarassed if you found out it was for porn, or something else. Besdies, she can always go to the library. I did it for many months when my puter was on the fritz.

Keep her out of your space.
