Mike Trout shared his feeling about his long-time friend and brother-in-law Aaron Cox Thursday in an emotional social media posting. The Los Angeles Angels star remembered his fellow Millville native and high school baseball teammate as his best friend and the life of the party.

Here's Mike Trout's heart-rending Instagram post to his friend Aaron Cox...

Aaron, words can’t describe the emotions that I’ve been feeling the past week and a half. You were more than just my brother-in-law... you were my best friend. You made such an impact on my life since the day I first met you. You were an amazing person inside & out that showed us all how to live life to the fullest. Seeing and hearing about your impact on other people are all things that made me a better person every single day. The things we have done together like hunting trips, family vacations, golfing, fishing, and all the fun times we had together I will cherish forever... you brought so much happiness and joy to my life every time I was with you. You will always be remembered for your crazy dance moves and your big smile and how much you cared for people and our family. You were always the life of the party and you were always making people laugh. You were a great kid and it kills me to know that you are gone... I can’t thank you enough for what you have meant to me over these last 11 years. I know you will be watching over me now that you are gone, I promise to take care of your sister and watch over your whole family. Heaven got a great one and I know I will see you again someday... I love you bro!!!!
