One of the things I pray for is my nephew to have a secure life full of love, so that they aren't pushed into some of the scenarios and resulting relatively harmless but nonetheless questionable choices that I've made.
I want them to be able to choose the right thing secure in the knowledge that even if it blows back on them they are safe enough in life to withstand it.
I want them to be able to grow rather than just merely survive.
Having someone in their life like you who wants this for them (and knows some of the harder paths) will help them a lot. Knowing someone has your back and wants the best for you is one of the most important things. They are lucky to have you.
