I'm not techno-savvy. At all. Even when texting I spell everything out. I don't understand a lot of the acronyms, granted I've worked out some of them.
I AM shy. Socially phobic, even. I never know what to say to anything, or if it's acceptable to say something or act someway. It sucks, but I've learned to live with it. Sort of.
When I post something, I usually have a bit of a meltdown. First, comes the "I actually wrote this?", and then "I can't believe I put it where people can see it!" I guess it's just my process.
