Few facts of living with her majesty subjects (The one I know are young, most of the time students and with some notable exceptions show the same kind of behaviour.)

• They don't like to cook, likely because they don't know how to although the UK TV channels are full of cooking programs. A typical meal prepared and enjoyed with delight by all the English is baked bean on a toast with some butter.  Disgusting...

• Politeness is not something they usually consider when they meet people. Words such as Hi, Hello, Good bye or whatsoever are not very frequent. Typically, they can ask you something about you and not listen to your answer. They don't feel that they should give you anything in return if you have given them something or helped them. Even not an acknowledgment. Bastard.

• They have also this mysterious ability  to disappear without any explanations, even if they have given you an appointment. It's better to learn that when they say "Yes" it really means "may be" and "may be" means "no". "No" means generally that you have upset them.

• Most of them are all in love with a club of football since they were child. They are going to watch consciously all the matches they can are argue endlessly about club, player, cup, weather...  Boring.

Of course there are exceptions, I have a couple of english friends that don't fit completely in this stereotypes, but they're rare.
