It's a shame that you feel that you have to lie to feel accepted..but I can relate to what you're meaning.
Maybe, suggest that you "dabble" in home with your computer. That isn't exactly lying, as you're obviously using one to access this site to post?
You don't need to be specific as to "what" you actually DO with your computer...just leave it for them to fill in the blanks. IF they should push the issue further, then just say "I do a bit of this and that with my system. I'm just beginning with it so it's still new to me "....and leave it there?...Something like that?
Usually,when someone asks me what I do with my time while I'm in home, I just tell them...."a bit of this and that"...and I leave it there. IF they push it again, I repeat myself....LOL...(as it's none of their business, anyway).
Hope that helps a bit....
