We are selfish beings and expect people to cater to our needs all the time. But thus the nature of relationships. We can't always expect to receive. We gotta give and sacrifice too. We can't control people and expect them to follow our standard. And when people disagree, we sulk. We are not robots or pawns. We are free beings. We gotta respect that and maintain peace by accepting our differences. If something is not right, it's good to stop and reflect - what did I do to contribute to this crisis/issue? What can I do to make it right?

Seriously, who got time to pujuk a sulking adult?
