Maybe you should do a test to show them how trustworthy you are. For example: take an egg and tell your parents that you will take extra good care of it and don't let it crack for a week. Make it a hard boiled egg so if it does crack it won't be a gigantic mess. If you keep the egg from cracking your parents will know your are responsible and trust worthy. if it works celebrate with a tasty egg. If you are talking about your parents knowing whether you're lying or not then all you have to do is just pray to God to always help you tell the truth and also ask him to help your parents to trust you when you aren't lying. If you are a worthy servant of God he will be happy to give you a helping hand. I hope I was helpful to you and good luck with your parents. May God bless you and help you.
well you probably did something to break there trust...if you didnt and your sure you didnt they are just looking out for you or making sure you do the best in there eyes but if you like that have a talk with your family about it. hopefully this helps
This is what i did: gain there trust by saying ur goin to Lunch or somthing with say like three friends an tell them who they are and ask if ur parents could go save a table or something. Once they see ur with the ppl u said u were going to be they will trust u more
