My father passing away when I was 10.
This is also my answer. But believe it or not - it wasn't an all bad thing. I loved my dad so the loss was hard to take. I had a great 10 years of being the youngest child in a upper middle class family. We took family vacations and ate out at nice restaurants fairly often and I had everything a kid could need and most of what a kid could want. Then one day that all changes. My older siblings move out of the house within a few years and it is just me and my mom on our own and living a fairly frugal lifestyle. The good things that came out of that were mostly just me realizing how great I had it and wanting to experience that type of life again. I have a great family of my own now and because both my wife and I work at decent paying jobs - our kids are able to have the same advantages I had for the first ten years of my life. Now when things are tough at work or home I realize how lucky I am and things don't bother me as much. Today I get to experience with my family all the things that I had and lost earlier in life. And I think I appreciate my family more and am a better husband and dad because I had experienced such a great family lifestyle and then had it all taken away from me.
