I was talking to some of my comrades in the camp, when one of them started asking me about my current game project. I told them the best I could about the game, and they seemed to be interested. It was when I kept on discussing about it (more like rambling on and on..., in my opinion), that I started to get a weird feeling in the back of my head.

That feeling, described as a "spider sense", was telling me that I can no longer communicate clearly with others anymore.

I usually get these feelings when I'm talking about technical stuffs to others who aren't into software development and IT stuffs. The more I get these feelings, the more I become afraid. I'm afraid of myself not being able to stay on par with the outside world, not being able to communicate at a level where everyone else can easily understands me, and not being able to stop when I should really stop rambling.

1. You ever had that sort of feeling?
2. You ever had that sort of feeling, but in the other way around? (You're talking about what you know, but your listener starts telling you that the listener can no longer understands you. Or you're alienating yourself unknowingly.)
3. Have you been able to overcome this?

Have you ever had the feeling that you just can't communicate clearly with someone else?

I've never had the feeling that I can communicate clearly with anyone.

Of course you need to realize the level of expertise the other guy has. But repeatedly asking "are you still with me" or "did you understand" is quickly considered rude and patronizing. That's why I've deduced the best is to take a breather and give the other guy the opportunity to ask about, expand, and direct the conversation as he would prefer. It's likely he will stop asking technical questions once you've gone in more depth than he can handle. Then you can stay on "that level" and discuss some of the other areas you possibly have in your game :)

Tbh I feel like this with most people about anything, well outside densely populated regions. Seems any discussion results in confusion, maybe it is a cultural thing, I dunno.

I think I might just be missing the city too much and becoming ridiculously bitter tbh /sigh

You definitely should remember a couple things though...

1) You're part of a generation who in general couldn't tell you the difference between your/you're, there/they're/their, or to/two/too...

2) You're part of a generation who in general would spend 15 minutes writing a text, than making a 3 minute phone call...

3) You're part of a generation who in general gets all their knowledge and opinions of world-events through Facebook...

So don't expect those people to be able to hold a remotely intelligent convo for more than about 90 seconds.

We were on a group project together???
