Honestly, I totally believe there are some great Leos out there! But saying it's your problem if you havent crossed paths with that energy nah, I dont really agree with that. There's the ones thats still growing and figured out stuff, and theres the real ones.
My whole family has Leos in it honestly, my mom, one of my big brothrs, an aunt and an uncle too. And from what I've seen my mom might be the most giving and kind person I know. Not my aunt though, shes really just self important and everything always comes back to her. She's done so many dirty things just to win an argument or get what she wants honestly.
Then my own experience you know, I was married to a Leo man and just ugh, that person was so terrible I honestly still cant wrap my head around how a human being is capable of that to someone else. Whatever it was it caught up to him, just in a lot of different ways and atleast thats something I suppose.
But you also have to look at bigger picture things right. Every person is different so reading just your sun sign really just skims the surface honestly.
