Can Piper and Jason be kind of jerky to Leo?

They act like he's not there, ditch him and Leo considers them his "best friends" just because he's known them longer! I feel like Hazel and Frank are better Những người bạn to him. While Frank too was a bit of a bully to him, once they resolved each other's differences they actually ACTED like Những người bạn towards each other. They actually acknowledged each other's existence.
