One never should mock their child, be supportive and help them out. Now, I don't know what moron doesn't know that Everest borders Nepal and China. I might know that more than most because at one point in my life I considered climbing it. Then I regained my sanity...
Just me, but why would parents mock her when they themselves are clueless... I think it's great that you help your daughter. It helps her learn and strengthens the bond between the two of you. I remember helping my son out and figuring out just how much I had forgotten since I was in school!
