Okay, I just reawatched the end of that video, and now I remember what I was thinking about. 

At school, since there's literally one week of school left, Ms. Leeper and Ms. Gray have been letting us play cards during class. 

After I actually figured out the rules, I was pretty good at them. I won Uno two out of the three games we finished because I could see other people's cards and I had good strategies.

I won a game called something I'm not allowed to say three out of the three games we finished. You take turns placing cards face down in order from Ace to King. If you have more than one of the card you're supposed to put down, you put all of them, but if you don't have the right card, you can lie. If you think someone is lying, you call them out on it. If they weren't lying, you take all the cards from the middle, if they were lying, they take all the cards from the middle. The first one to run out of cards wins. I won all three games because I never called anyone out unless I was completely sure, and I didn't let anyone see how many cards I had, because if someone only has one card, it's very unlikely that they're telling the truth. 

Although, I did find out what my tell is for when I'm lying.

I won one out of the two games of Slap Jack we finished. During a game we didn't finish, Will only had one card, and we all knew it was a Jack, but I somehow slapped it before he did and then he was out. 

CARD GAMES RUIN FRIENDSHIPS

Especially Uno. We were playing using "Super Fun Rules" as Ryan like to call them. So whenever someone put down a seven, they had to switch decks with someone, and if they played a zero, everyone had to pass their cards to the right. Every time someone did that, It would make someone give up the best deck, and someone else get the worst one, so we all were saying "I hate you" a lot.

Then in the game where you call people out, whenever someone had to take the middle deck, they hated someone.

Then in Slap Jack, whenever someone lost they were very upset with themselves.

Basically, if you're in a group of people who get mad or fight a lot, refrain from playing card games.
