Classical Music Etiquette for Dummies

As being in many classical music concerts, I somewhat get irritated when seeing a few members in the audience who haven't followed proper etiquette during the concert. Thinking about it, I thought it might be a good time to write a few things I've learnt over the years in simple words :P

1) Turn off your mobile phones (easy, but why can't people do it?)
2) Don't talk during the performance.
3) Don't applaud until the whole house does (so that you don't have to know the difference between movement and pieces)
4) Wear warm clothes (As most concert halls are cold this is recommended)
5) Don't make too much noise (e.g. eating)

Hmm.. well I hope I didn't forget to mention, enjoy the performance :P
