What is the attitude you to friend who do not know reciprocation?
For example: I've helped my friend get a job when he was unemployed, but instead after she had a job and I was unemployed he did not help me get a job when I've asked him. worse still he did not pay his debts after me give you a loan even though I already collect.

Unfortunately, in our time there are a lot of bad and greedy people. It is necessary to do good deeds and not to demand anything in return.

You may need to think twice about the friendship.

I do not demand anything in return from him, I just questioned the attitude of friendship like this, the problem is this people do this to other friends who are not just to me. So here I would like to ask for advice to you, should be how my attitude to friend like this when we met?

You may need to think twice about the friendship.

Luckily I do not repeat this mistake again in friendship.
