Why everyone I met like playing push&pull games? Blowing hot and cold, replying late, or even cancelling plans repeatedly. I can recognize their tricks at once but I still don't to be that kind of person. Honestly, I find it quite disrespectful. It makes you feel like you don't even deserve the basic respect. And it's such a waste of energy. I'm so tired of all these tricks. Why can't people just be sincere?
