Be ashamed of

[Jazzy]

What should people be ashamed of for not knowing how to do?

 

[Smiley]

Saying "please" and "thank you", although people generally know how to that, but prefer not to.

 

[Jazzy]

How to remain quiet. I don't even necessarily mean to just be respectful of other people and not making a lot of noise. I mean some people just have to say something, especially in bad situations. Just shut the heck up.

This quote comes to mind:
"Speak only if it improves upon the silence."

-Mahatma Gandhi

 

[~KAGE-008]

Interrupting the conversation when other people are involved. However if this happens with people who have the Aspergers condition, this might lead to them speaking to themselves. Which is something I hate too.
