Lifestyle

1. Language

Never make fun of others' language including words and accent. It is their mother tongue and nobody will like it if you are insulting their mother.

2. Food

Do not give negative comments on the food they are eating. They are not going to change their eating habits or the food they have been eating since childhood.

3. Religion

Respect their religion and let them follow it. Do not comment on it as it will hurt their feelings.

4. Comparison

Last but not the least, never compare your financial status, education, health, children, successes, wisdom and situations with them. It will do no good.
