The second text is about making a team training plan. In the first text, if things go well, people will meet again.

I think the note is for an old classmate or friend, and the voice message is for a teammate. Let’s talk If your friend doesn’t answer your phone call, how will you communicate with him / her? If there is no time to text, how will you communicate? If you want to thank your classmate but she is absent, how will you communicate with her? We communicate in various ways.
