I was six years old then.
It's interesting that you bring this up, because I've thought a lot about this myself because I had a friend back then that have I am now gaining back.
That year, me and my parents transferred churches. My mom had been at our old one since 1988, and my dad since 1993. In fact, they met there in 1996 and got married the following year. As a result, that was the very first one I attended, as I was born in 2000. However, when I started my 1st grade year in August of 2006, they switched to a different one, and that's the one we've gone to since. Well, when my parents began dating in 1996, they met a married couple, who later had a son the same age as me. He and I were friends up until when they made the decision to change churches.
Well, this past November, during my sophomore year of high school, my geometry teacher got fired, and, after going through seven (yes, you read that right, seven) different substitutes in November and December, we got a new teacher. She was my old friend's mom, and told me it had been 20 years since when she first met my parents.
Me and my old friend are slowly becoming friends again. I wouldn't say we're close, but we're getting back to where we were back in 2006 and earlier.
This ties into how each year from 2006 to 2012 was one where my life changed a lot, going through strings of friends and so forth. But, by far the biggest change in my life in 2006, aside from switching churches and losing contact with a friend as a result, was when I no longer saw a girl that I had known since when I started preschool in 2003.
She and I were in preschool from 2003 to 2005, however, she did go to the same elementary school as me and was in my kindergarten class during the 2005-2006 school year. However, after the school year ended in May of 2006, despite the fact that she and I went to the same elementary school the whole time, we were never in the same classes up until my graduation from the school in 2011.
However, in August of 2011, right when I started middle school, she and her family transferred to my church (the one me and my parents have been going to since August of 2006), and she soon began having feelings for me, which was awkward because I didn't feel the same about her (at that time, I had been liking the same girl since February of 2010), and all the time she talked about how, during the time that we were in preschool and kindergarten together from 2003 to 2006, I had said to her that I wanted to bring with me to New York, as apparently I wanted to move there then.
How this relates to my life in 2006 as that I was a year that was a major transition for my life. Although the transition to elementary school had been completed the previous year, transferring churches and losing contact with two people that I knew well at the time (one of which was a good friend) proved to be a major shift for me. The only other year I'd say where my life changed as much as it did in 2006 would be 2009.
