One of them is to have friends who aren't so immature mentally wise. Like, when they treat a person and talk bad about them by only with the impression they've given off, when they clearly don't know who they really are and what they're going through. Especially when they don't even know each other. It's irritating and too immature. Another is being with the people you love and care for who do in return. And being able to love yourself first before anyone.
