I called my colleague, but she didn't answer or return. What do you mean? Should I call again?

In this case, if you call and he doesn't answer, don't call. Because you call him and he doesn't answer, if he turns on his mobile phone without listening, he will instantly see your mobile phone number showing missed calls. If he is interested, he will reply to you directly and ask you. What's going on here? What happened? He'll ask you. If he doesn't call you back, don't call again. People are bothering you. Afraid that you will appear in front of him. As you can see, our usual feelings and sixth sense are actually correct. Maybe you asked the wrong person. In fact, in order to survive in society, we should also keep our eyes open to see if we can make friends. See if it varies from person to person. These are extremely important, because a really good friend is always there when you are in danger or have something, and will answer your phone at any time. This is a real friend, a real buddy. It's not that he can't hear you when you call, but that he doesn't return when he sees you. It's also called buddy. Let's call it a passerby.
