Never Trust Anyone

Please correct my grammar and punctuation mistakes.

I was talking to someone and he advised me never  trust anyone'. I asked him even your parents and your life partners. He replied, "I said never trust anyone". He also gave me an example that a father put his son on wall and asked him to jump down. The son said "I can't"  but the father said "I will catch you don't worry. Just jump". When the son jumped down he didn't catch him. He complained to his father "You promised me  (that) you will catch me". The father replied "Didn't you remember I said never trust any one ?".

I am bit confused shall we really not trust our parents and loved ones. Can anyone help?

Notes: Some of the sentences were ambiguous because you were using he to refer to two different males. I have highlighted in red and italics, the conversation words in your example.

My answer to your final question. We humans do tend to trust each other. However there are certainly untrustworthy people in our midst. I think that the father could have used better methods to teach his son the value of discretion.
