Let's start with this new student. My idea is that since my colleague invited me, it doesn't matter whether I go or not. Of course, if you have something, we'll talk alone. Besides, you must have invited more than one colleague to his wedding. You just came to this company, and you certainly don't know much about many things. Maybe this wedding will bring you closer to everyone. But it doesn't matter if you don't want to attend the wedding and other activities, but after all, we are invited by others, so we can politely tell others that we won't go. It doesn't matter. But when this kind of thing can't come, you should say it in advance. And I think my married colleague will be so angry, probably because he thinks you have humiliated him, whether at work or at home. That's why I'm so angry.
Let's start with this newly married colleague. In fact, he needn't be so angry. New students may just have something to do, and this marriage is for happiness. It is not good to make such a fuss. If we have any misunderstanding, we can explain it slowly in private. Besides, people don't want to attend your wedding, so you don't have to be angry.
At present, inviting colleagues to the wedding is more for the money in hand. Of course, we don't rule out inviting them to make friends and let everyone know each other. It's just that in this material society, true feelings are really hard to admit. Other weddings invite colleagues because they are afraid of not inviting them, but only afterwards do they know that things are even more stiff.
Marriage was originally a happy thing, but because of such a small thing, it became well known and intimate. It's not worth it.
