Dear children,
Not everyone in this world is going to like you. In fact some people will vehemently dislike you, sometimes for no apparent reason and with no explanation. Others may dislike you because they disagree with your opinions or have starkly divergent worldviews, or simply because they find your laugh to be the most annoying sound in the world. Or it could be that you were more successful than them in some way or another, or you stood up for yourself when they thought you'd been crushed into compliance.
Whatever the case may be, you need to know that the world is not a perfect place and there are plenty of mean/unfair/unjust/cruel/nasty people in it. Its just the way it is, I'm afraid.
The important thing is, you don't let this affect who you are. You should still be kind to everyone, even those who are less than kind to you. Be fair and just in your dealings with everyone, even when they have tried to cheat you. Do not let envy into your heart, even for a moment, because it will consume you, casting its shadow on your soul. When someone hurts you, forgive them, pray for them, but keep your distance from them, not out of hate or resentment, but to protect yourself from further hurt. Always stand firm against their attempts of oppression, have the courage of your convictions, and fervently seek to expose the truth.
If you feel that someone is bullying you, stifling you, coercing you to change the things you hold dear, hold up a mirror so that they might see the ugliness of their behaviour. Never respond with anything less than goodness. But if they refuse to see the error of their way, then tell someone, find support. Then leave. Leave and don't look back. Leave and ask God to give you the strength to grow from that trial, to keep your heart soft, and to protect you from their grasp.
Do not allow these things to affect the lens with which you view the world. For every mean man, there are many kind men. For every unfair or unjust man, there are many many men who uphold and promote fairness and have made it their life's work to fight for justice. For every cruel and nasty man, there are countless good, gentle men. Those whose spirits align with the fitra in which they were summoned to this earthly world. Take comfort in that.
Take comfort and never stop hoping.
Love,
Mum.
