Not just our perception but even when people do wrong to us. You avoid them in your life and your respect diminishes but it shouldn't fade away. For ex., in your personal life - your ex-es, best friends, relatives, in work life - boss, colleagues.
Very True, Couldn't agree more.

Oh my bad! I just read the headline question and your pointed reply. Now to answer to your extended question in abstract,
1. Respect elders and treat old people with utmost care and love
2. Your visitors comes before you in everything
3. Basics are very important - grammar, discipline, habits
4. Question - if you don't understand properly
5. Never repeat your mistakes twice ( using updated version only) :P

However, my reply is a multi-learned thing from real life experiences.
These are really nice habits to follow, you have learned very valuable lessons in your childhood.
