One of my favorite proverbs is " People who live in glass houses shouldn't throw stones.' it means that you should not criticize other people for bad qualities, but you still do it. It's often said when a person who always blame or judge others by not watching their self. A similar proverb in Thai is "ว่าแต่เขาอิเหนาเป็นเอง". This sentence made me think before speaking. Whenever that I will blame or judging other people I will stop, and think am I good enough to go to warn others?
