What are you afraid of?
Failure. In my opinion, there is nothing scarier than doing all you can and not have any of it work. It applies to everything -- family, love life, video games, windows troubleshooting, friendships.
That last one is definitely underscored to me in my book. To this day, I still think that I've failed at a lot of the friendships that I thought were tight-knit. Even though sometimes it probably wasn't my fault that there was a falling-out, I feel upset to my stomach to know that I can't even be friends correctly with people. That something I unknowingly did has swayed someone's opinion of me for the worse. It hurts to know that someone hates me or just decides to not talk to me on the level that we once did. And I reach out only to pull back a few broken fingers.
It's hard to just let it go like I left that emotional front back in high school. I was always "that guy people knew" in high school, not necessarily a go-to-guy, but just some dude that everyone knew of. With the exception of two or three people, I didn't have a stable of friends that I could kick it with on an hourly basis. I thought I could shed that as I got older, but I feel it now with a different set of people in my life and it sucks and there's nothing I can do about it.
...I never know where I go when I write like this. I just end up typing a whole bunch of stuff and half the time I erase it and cancel the entry, the other half I save onto Notepad and never publish. I just know that I wish that it was a couple years ago where all my good friends were still my good friends, and not just "people that know of me".
