Different people have different standard of what it means to be fluent in a language. I would say that if you can comfortably have a casual conversation you're fluent. If you're fluent in 2 languages I would call that bilingual. You don't have to be as good as a native speaker in both languages.
English is your second language and you typed a pretty long post in perfect grammar so I would say you're bilingual.
When I was about 12 I had a computer nerd friend who used linux almost exclusively. I used various linux distros at his house. I don't know what they were.
He gave me a knopix CD so I could use linux too and that was the easiest way.
I thought I'd try linux myself so I burned Ubuntu to a cd and tried to install it on a family computer as a dual boot. I did it wrong and deleted everything. My dad is a computer network specialist so he understood what happened and wasn't mad. He made a backup of the family computer a while ago and restored it. We still lost some things, but not everything.
My friend got me a desktop computer for free and put SUSE on it. My parents wouldn't allow me to have internet in my bedroom so I just played games and made stuff on blender with it.
My friend also got me a free laptop at this computer nerd conference we went to. We listened to a bunch of people talk about computer stuff. They also had free stuff we could grab. I got myself a laptop. It didn't have an operating system so my friend installed Ubuntu on it for me.
Eventually that laptop and my desktop stopped working and I never used linux again. After reading about linux here I started to miss my Ubuntu laptop and I'd like to try it again, but I don't want ruin my current laptop like I did with the family computer.
I got a really girly looking beanie (I'm a guy) at a white elephant gift exchange and it became my favorite beanie. It got stolen and I'm sad that I can't find it again.
I miss how big reddit was. There were so many niche subreddits that were active. A lot of them are still active now, but I also don't want to support spez.
