I get the same thing..... "Quit playing on your computer", "Who are you talking to now", "You pay more attention to your online girlfriend than me"..... and so forth, lol. That's why I have an office now
If I am working at home I go in the den and shut the door.... she knows I'm working for real then. I finally showed the gf what all I do online and that chatting with people IS a part of my job.... she is a lot more understanding now.
