i remember having a party a few years back, and it went on for 2days... when it got round to cleaning up i came across broken stuff all the time and had to find a way of *covering it up* nothing really expensive was boken luckly, just picture frames and other stuff like that... its amazing how superglue can fix 99% of household objects, and to this day 90% of those things have not been found to be broken (most were only minor damage anyhow) :D shhhh its a secret...
end of story if your gonna have a party etc you have to expect things to get broken, its not your friends fault really. Anyhow go get the superglue out.
