I admit, I would troll him a lot. I am a goofy person. So a lot of [these photos and videos] come from this goofy side of me that we shared," the 28-year-old shared."All these memories I have of him are of us laughing, and they're good memories. It hurts to look back at the photos, but I'm grateful that I took them because it reminds me of the good times I had with him, and I'm fortunate enough to have that documented."
