First of all, I'm going to correct your sentences.... --->If your parent doesn't(parents don't) understand you,what would you do? if you want to do one thing or made a mistake,your parent doesn't(parents don't) support or understand you,what would you do? my answer: Apologize first if you made a mistake. Then try to compromise or discuss any disagreements you guys are having.Restrain yourself from getting angry because that probably won't get you anywhere(haha, arguing never works for me even though honestly, I sometimes do anyway). If you made a huge mistake that your parents are exceedingly angry about, you can still apologize and discuss it but it'll take time before you can gain their trust back.

Its like any problem. Problem is to be solve with solution. You have to work on the solution to make them understand you and at the same time try to understand them. At time you need time to prove your solutions, but most importantly, you must win their trust and confidence in you.

Our parents always wished us the best. Try to calmly explain to them what you want.

if you want to do one thing or made a mistake,your parent dont support and understand you,what will you do? how this ,, you want to made a mistake?? and you want them to understand !!!!!!!!!!!!!!!!

hi , I will try to convince them.
