Always help someone when the opportunity arises. You might be the only person that does. Remember, nothing is random in your life. The Almighty has arranged everything.
Sometimes people will say certain things to me in passing and I won’t even notice an issue until I’ve been able to mentally process it later. Eventually I’ll be like “wtf 🤨” but bringing it up later will look weird, so I get mad at MYSELF for not calling it out in the moment!
