Leave me alone

I don't know why some poeple always like to make "funny jokes" at others,
even that person done nothing wrong!WHAT IS YOUR PROBLEM?
"I'm not going to London because I've got too many work to do."<=is that funny?
Is there something wrong if I don't want to go to London?
How old are you guys?
Still talking bad things in front of the person you don't like? Like a primary student?
If you guys like to say bad things of others, say in English then! NOT CANTONESE.
Let everyone know how strange, how funny I am, share your funny jokes with the whole borading house then! I don't mind it.
I can hear you guys talking about me, every single words, I can heard them clearly.
Go on then, keep talking problems of people, you guys are doing very well.^_^
