Question: what are scabies? i have a friend who just called and saud she has them...should i let her over my house? 

Answer: OK, this is kind of gross.  Scabies are actually tiny insects that burrow under the skin and cause redness, rash, etc.  It's easily treatable, though, so don't cut your friend off! You may want to see your doctor if you start itching, though.
