My heart goes to you man. It's hard to lose someone you love and care about, then the thoughts and(regrets) the things you wanted to say to them come and go. There has to be some kinda energy connecting us to feel weird feelings like when a close person passes or stresses.
The main thing is you had that person in YOUR life and it dont really fade from your memory bank. All the kids on here must think their parents, grandparents dont die..Or they just have no ounce of respect.
Well brother, pass on what you learned and make his torch brighter by shining his will to the world.
Be the reflection he would be proud of.
