My friend said that the internship was finally over. How to return it?

You can reply: I wish you a pleasant journey, smooth sailing and further progress after your internship. A friend said that the preparation for the internship is finished, which means that the other party is about to start a new journey, and at the same time, it will be very busy. You can find time to chat with each other, share your recent experience, and send a message of blessing to each other, wishing them a pleasant journey in the new journey.
