Can confirm, this is how my brother and I act. Especially that first one!
Btw, I love the way you do expressions. Even in little doodles, they always seem very detailed and how I’d imagine a character to look while speaking. It’s really good!
Also I love how Lumino breaks the whole ‘mainly expressionless’ look just to be salty about being short. You’re still short, Lumino, live with it x3
