It's pretty amazing as you get older and look around at how much has changed around you.
Friends, they have grown with you or grown away from you. No matter how much they're still the same they're never exactly the same as they once were. Some move away, and some stay. You stay more in touch with the one who moves away then you do some of the ones who stay in the same area.
Environment, Buildings come and go. The places you used to visit are no longer there or have changed from what they once were. Our old hang out arcade Fat City has changed twice since we used to go there every weekend and play DDR until they kicked us out. It changed once to become Mr. Bigs, and is not Fun City. Sadly, we went there the other day and the DDR machine is no longer there.
Relationships, Another thing that comes and goes. Until you find that one person you want to spend the rest of your life with. Who you look at, and think of having children together with and it brings a warm smile to your face. Who no matter what arguments you have, you can't help wanted to smile when you see them. We learn so much from the people we have relationships with over time. Sometimes we learn more than others.
Family, If you're lucky, they are always there. They always have your back. I used to think this was the case with everyone. That everyone was as close as i am with my brother and sister, and have good times with their parents. I've since learned this is not always the case. People fight and never see any reason to make up. However even family changes. I had my first close family death this year. I have had great grandparents that have passed away but i was so young, i barely knew them. If i even met them. But 2 months ago now, my grandfather passed. I was maybe 6ft away when his body stopped, and i was the first to wake up and realize what happened. I will always miss him, and if there is an afterlife(something i'm sure i'll touch on sometime) i hope he is enjoying it.
we'll see where this goes, maybe it'll become something i post in regularly. we'll never know until it happens.
