I don't understand why people are so afraid of communicating like adults. Don't like someone? tell them. Don't wanna talk to them? don't ignore them. You're mad at them? express yourself. They’re wrong? explain. You don't agree? share your viewpoints. it's not that hard lol.
Introverts don't lack social skills, they're just not interested. They can talk. But not with everyone. They need the right mood, the right place, the right person. They need to feel your vibe and trust you. Then, they talk.
