Improvement in handling disappointing others

So yesterday i went to my mom’s to celebrate Father’s Day.  Back on Mother’s Day, I forgot to get my mom a card...but had remembered one for my step dad.  This led to a bunch of comments ( stated in a silly way) about this (such as my step father asking if he should display only my brothers card and my brother joking that I must love my step dad more than my mom)....before, it would have hit me hard....I would have felt guilt to the point of shame and would have driven home angry and resentful......but....this time, I just acknowledged it as a mistake and then just let it go.  This was huge for me and I am super proud of the work I am doing because it is bearing fruit. . Just wanted to share.
