You stand in front of someone, how you talk, in Chinese or in English.

You go to your own bathroom yourself.

You check on your own property yourself

You go to the car maintainance yourself.

You grocery shopping home yourself, if you living with you own giant faces, no more guys. Just deliver a job, endless lawsuit.

You take care your mother's plants. 

You wash her sink....file her reports. 

You know what it means when someone seeing you, just seeing you the first time, you don't give the people's feeling, you don't need to lean on them.

Not in language "daddy daddy, uncle uncle, can you go and tell Anna that....?!"

Not in language, "Its the saleman says the price on, you are my glory, pay it, so I spent it. I didn't know what to say to them."

Design

I never think there are design issues. Its the money issue, not the design issues.
