"Well, with your bad knee Ed, you shouldn't be throwing anybody......".......8) Think about why she doesn't trust you.....if you don't know why she doesn't trust you, then sit down with her and have a chat......all in all, just try to make good decisions, and with a little luck she'll notice.....
Ask her to trust you with something small like doing the dishes, and then something a little bigger, like babysitting. And then eventually you will have gained her trust back, you will have to earn it though. There is a saying, "Trust is not given, trust must be earned." Good luck!
a punishment many parents use is the you dont have my trust anymore punishment. your mother might have told it to you and it might be true just be good for a couple of days and do exactly what she asks then when she is in a good mood ask for forgiveness and ask her to trust you again
Actions speak louder than words, and like Katwhiskers said trust is something that is earned, just like respect, unless your mom is just this very unfair human being, you've obviously done something(s) to earn her distrust. So now you have to reverse that and earn her trust back. But know that it's not going to happen overnight, keeping your word to her, and if you can't you MUST communicate that to her, and it should be a justified reason, honesty,no lying-tell the truth regardless...and be genuine. You will have to change your thinking and eventually she will see through your actions that you have changed, and the trust will be there.
The best way to gain trust is to act in a trustworthy manner. Here's the the thing you must understand, once trust is broken, it takes TIME to regain it. She loves you and wants to trust you. It's not just important not to DO things that erode her trust, it's important to also not behave in a way that appears untrustworthy .
