(2)They’re asking for it

(5)Since middle school, the five of us are close. I declared non-marriage since I was young based on my belief, except for this
(6)He got married. He gave about 30 to 50 congratulatory money per person. The problem is that he wants us to give him 10 for his long overseas trip this spring. He’s going on a trip to celebrate his 40th birthday, even if he doesn’t earn as much as he sprinkled, and his friend made a lot better than us and gave him gifts such as a first birthday party. But I want to hear from many people whether I’m weird or if I should follow the changes in time
