I know grown ass people who say “this just the way I am” alllll the time
Recognizing your own toxic behaviour is peak adulting. You don’t stop learning once you turn 18+.
My dad is almost 70 and always says he’s still growing, changing, and learning. That’s what life is, an ongoing experience that you gotta be open for change in.
“That’s just how I am” is bullshit, you don’t like it or you see it affects the ones you love negatively, you change that shit.
