Be serious in doing things

Don't we often overlook details that can cause unnecessary trouble

? Just today, I accidentally recharged the wrong phone credit... which affected her mood. It was just a joke. If I hadn't been topping up your phone credit, would I have made that mistake? It was just a joke, yet it affected her mood. She takes things too seriously. Haven't most of us made this mistake? I should avoid saying it in the future. If I hadn't recharged her phone credit via WeChat before, would this have happened? Also, I wasn't careful enough. I should have checked earlier. I used to use my own phone number, but I didn't change it when I recharged someone else's. I should remember to check carefully before making decisions in the future.

Also, regardless of the relationship, paying back debts is a matter of course. Even close brothers need to keep clear accounts. It's like forgetting to pay back what you borrowed. You forget what others owe you, but why don't you remember what you owe others? That was before, every single transaction is settled. And then there's the issue of transferring too much or too little, with the excuse that it was just right. If you're so capable, don't transfer too much! It's just a few cents. It's best to get it over with; things shouldn't drag on.

Everyone has minor problems to some extent; it's all about how you deal with them.
