I bet you don't even know about the color fill brush.

Today I have leveled up my nerd skill, I completed a chapter of some sort of DnD-like. It was alright; I can kinda see why you like those R2D things now.

No way, I had my first D&D on Wednesday. Weird.

Tabletop games are cool but also depend a lot on your GM and coplayers.
I've not done all that much though either, and never actually DnD.

I played DnD when I was a preteen but then I started acting hostile towards people and I didn't have friends to play with during the following years

I don't have friends now but I can talk to people, so that's good enough, right? Like, good social skills. I just don't like having friends.

I think I'd be a substantially worse person to be around if I hadn't made the friends I have, and also much less happy.

Yeah I'm kinda getting over a phase where I thought I didn't like/need other people myself. Friendship is often pretty tedious but now I've re-realized that it can be worth it.

I know I joke about it a lot but I think I have actual trigger words.

Having friends is nice, most of the time.
I do get burnt out though, and then it's good to just sit in front of my computer alone for a while.

Friendship is magic.

AND THUS, THREAD GOES FULL CIRCLE AND BECOMES PONIES.

No but seriously, there's quite a few good points in there.

I really like this video.

This is kind of random, but today I tore or sprained something in my inner left leg while doing a split.
I had a warmup and have done them before, I don't know what I did wrong. It really sucks.

Sometimes when you make too much exercises or something like that (not sure), you get this huge pain on your body, I got it once, I couldn't walk, then after about 3 hours it started to get better.

Quick PSA time.
Warmup exercises actually usually do more bad than good, if done wrong. Stretching, touching your toes, etc is bad, since it makes your muscles go "Oh ♥♥♥♥ I'm bending in a way I'm not supposed to, better lock up." and thus more likely to get damaged.
A light version of whatever you're about to do though, that's fine. If you're going to be running, do some jogging first. Playing basketball, run around, do some jumps, etc. That's the proper way to warmup.

That said, I'm assuming you know this and you just hurt your leg, which sucks ass.
