Blood is thicker than water

There's an old saying which goes" Blood is thicker than water"- which means that your parents and other relatives will stick by you in times of need more than your friends will. Do you think this is true? Give reasons and examples to support your opinion. If you like, you may describe an experience which illustrates your point of view.

"Blood is thicker than water"- that old adage has always been true for me. There are some reasons to uphold my opinion: Friends can be unstable while parents and relatives may not and because parents and relatives are the ones who really care for us.
Friends can be unstable while parents and relatives may not. That is mostly true, especially in my case. Even who you call "bestfriend" can change because he/she usually receives the same pressure as you do. For those who are in adolescent, their bestfriends' mood are very easy to oscillate each and every day. At the same time, parents- who have already lived with us since the day we were born- is the ones who understand us most. Moreover, almost all our experience they have already been through, so they can give us advice and that helps, much or not. I myself do not want to confer with my best friend about my very secrects for fear of him revealing it to everyone the day he changes, but my mother. She gave me some good advice, though, and I am sure that she never told it to anyone else.
Although you may also whining about your scores at school to your close friends but in all probability, what we receive often are mild comments with several phrases like" Oh, I am very sorry to hear that" or "Try harder next time" or even pretend to have deaf ears and ignore our whining completely. Few really cares for others apart from themselves, but that is not in the case with our parents. They stand by us most of the time and give us good hints to help us resolve our problems. I remember talking to my mother about some bad scores I had got, she said that it is not the end of the world and she also had had many many appalling results back at school. She fostered me to go on and never give up or feel ashamed about those bad scores because I surely learned a lot from them. I think it was a very nice comment of hers.
By and large, I think friends do not understand us as much as our parents and relatives, so we have to count on them and never let them down.

I think you want to use unreliable or undependable rather than unstable. Example:

Your friends can be unreliable. Your parents are more dependable.

• Our parents understand us best.
• They have often been through the same experiences, so they can give us advice.
• I am afraid to tell my best friend my secrets because he might tell somebody, but I don't think my mother would do that.
• Although you might complain about your grades to your friends, they might not be very sympathetic.
• Few really care for others.
• You can count on your parents. They stand by us and give us good advice to help us solve our problems.
• My mother encouraged me to keep trying, and she told me that I was learning despite my bad grades.

When talking about your marks at school, say grades instead of scores.
