A colleague's father passed away. How can I comfort him?

this kind of thing must be done as soon as possible, preferably on the same day or the next day, so that it is most effective for him to receive your concern at the earliest.

you'd better use the phone!

SMS? ! It's ridiculous, the most insincere way to send a text message is to send it away for a dime? Do you take it as a New Year greeting?

Call immediately and say that he just learned the news (if he knew that you knew it for a long time, he would have avoided talking about it). XX, I'm sorry for your father's death. Don't be sad. People are born and die. Naturally, I'm sorry for my loss ... Take care of my mother's health, and you should take care of yourself. Don't worry about things at work. . . . Finally, he will say thank you, thank you and so on, and then you will say that you must pay attention to your health. Oh, I'm sorry for your loss. Uh-huh. In fact, as long as you are sincere, he will feel it. Why worry so much?
