I went on a blind date with a boy. After one date, he didn't contact me the next day. Just hopeless? What should I do?

Don't worry, maybe the boys feel embarrassed to contact you too early. Wait a few days. If you don't contact for more than five days, it's probably hopeless. If you still want to work hard, you can chat with him online on QQ number, or see him in Weibo, or you can find some problems in his industry and send a short message to ask him. If he is still half cold and half hot, most people are horses riding donkeys to find spare tires, so you don't have to pay too much attention. Just keep dating ~
