Why kids laugh at when seeing others falling/suffering?

Some time ago a teacher friend told me she couldn't understand why there were kids who laughed without helping when seeing a friend fell down.
Now I do. Coz there are TV programs which is showing how funny it is for people to fall down and there are parents who laughed together with them. Say if you are the one who fall that badly, right on your head/knee/or private part, how would you feel with people laughing at you?

To add on that, when you try to tell the kids that it's not alright to laugh at other people in this mode, there are parents who tell you bluntly that "Why dont you ask the program not to show up?". What kind of absurb adult?

Today I let a group of teenagers watched a movie clip on a real life air plane crash, which is about the last 10 minutes of life.
Some of them laughed in the middle of the movie when seeing the passengers falling and hitting.
Blame them to no one, but the TV program/virtual games with lots of hitting and dying, and the laughing parents behind.
I told them straight that you must be something wrong to laugh at someone who is struggling for life.
Frankly, I really do feel sick with teenagers like this. And I feel more sick to see allowing parents who show disrespect of other people feeling.

How To Get Rid Of Banking Telemarketer Annoying Call?

One of the most annoying calls during the peak and off peak period is call from bank telemarketer trying to sell their intangible products.

"Are you free Miss xxxx?"
"err... Short while ok."
"I would like to introduce you to our cash advance program. Have you heard of this?"
"Yes, This is the so-called legalised big ear lobe business."
"???? eee what is it?" took him some time to get back to recovery state, like the hanged Windows XP, then continued with background chuckle. "oh, not like that Miss xxxx." (forever polite with the right address, if call me Madam or Aunty sure i hang off immediately. ) "We wont go to your house and slash paint." (before this fella could finish it, i'd better slash him with my thoughts and scripts.)
"Seriously speaking, would you want your dear family members to engage in a financial situation where you would go for this program and then landed like shit? Would you? Would you?" (pestering for an answer.)
"No.....i mean.....you have to go for a proper channel."
"Oh then why should a banking institution not teaching consumers to manage their money in a proper way, instead of the shitty money lending difficult situation? Again, what would you feel if your family members landed in a difficult situation like they still cant afford to pay back?" (take a big turn and redirect this fella back to the question. All telemarketers really need to think hard rather than being brainwashed by their training program.)
"....... ..... oh ah....."
"Thanks for calling." (It's me saying this instead of this guy. )

Bye bye.....all telemarketers, you'd better bar me from your calling list.
Otherwise, I will give you a lecture on why you should change your job.
Scare you till die. LOL.

老爷刷着电话。我随口问: 上次你不是有只笔，可以写字的吗？
老爷瞪了一眼，眉毛翘了起来：那个是pda，过时了的。
是噢，这种在掌上的东西，看来看去就是一个款型 ---四四方方的。
俊男美女就不一样，款型有差别

Group mandala

Drawing a group mandala in the silence mode. 
An art piece by 4 persons at one go. No need preplan. No need coordination.
It looked nice to me, with some blend of harmony and disharmony.
