Be cheated of money by making friends and playing cards.
From your account, I understand that you often invite your colleagues, but they seldom give you back. I don't think such colleagues should get too close to them. They totally treat you like a big head. Even after you invited them, they spoke ill of you behind your back, which was simply not worth it. A bunch of garbage scum are not worthy to be human. It's not too late for you to wake up. Based on society, not by inviting guests to dinner. You are a sincere person, and there will always be real colleagues and friends to talk to you. So don't think about that, stay away from them, they don't deserve to be friends with you. It's already embarrassing for them to meet and say hello.
