While you don't need to suck up every crumb with a dust buster, you shouldn't leave chaos in your wake either. Communal activities such as meals are generally the responsibility of the host (though you should offer to help), but individual messes are your responsibility. Here's a list of some things you should remember to take care of:

• Make your bed (even if you don't do so at home).
• Tidy up the bathroom. You don't have to get out the Ajax, but do wipe up spills, fold used towels and keep your own items neat and organized.
• Keep your luggage neat, especially if your host's home is small.
• Put back books, CDs and any other items you may have made use of.
