May Day, summer solstice and summer vacation are coming, so I want to send postcards to my friends.

It depends on whether your friend is a man or a woman. You should write different greetings according to different people. Since it is May Day, summer solstice and summer vacation, it is inseparable from summer. You can write some sentiment words about summer on it. If it is not easy to write, you can quote some lyrics of songs with summer. In fact, these are secondary. Just write postcards with your heart. Even if the words are not so gorgeous and moving, the other party can do it. I often write letters and send postcards, and I still keep the habit of exchanging postcards with friends from nearly 50 countries. Welcome to exchange everything about postcards ... I wish you happiness. ...
