When friends visit

Something always goes wrong when friends visit, my past experiences are not good so I should not complain when my best friend visits and brings a didgeridoo! Yes that's right, my friend is flying in on Thursday and this is the worst thing they have done to me yet! Stop laughing at me! I can see it now, my friend giving my daughter lessons on how to play the didgeridoo, apparently he has got the videos of Ralph Harris giving lessons, yeah fun fun, spit flying through the room!
We all know my daughter is totally crazy about Australia, she has everything from Australian money, Australian clothing, caps, blankets, toy koala's, kangaroos, kookaburra's and now a didgeridoo? I am not sure what I need to do with this "friend" of mine maybe I need to put some kind of restraining order against them and Australian items!
