When a loved one transitions to the next level and they have trusted their all to someone other than you don't target that person negatively and blame them. The consequences of your actions may not be realized until that moment. Think about what you have done to contribute positively and negatively to their life. Just because you are blood does not entitle you to privilege. What entitles you to privilege is your relationship to that transitioned person.
So just when you think you have got by with your negative actions the truth can slap you in the face. What I have learned is to treat people with respect, care for those who show you favor, think about the consequences of your actions and you will reap accordingly. As long as you are within God's will you are safe.
Do the right thing because delayed consequences can be hard to swallow.
