Giving a meeting gift is a custom in some regions
1. Perhaps the groom's family does not have the custom of giving a meeting gift
Because giving a meeting gift is a custom in some regions, if you first visit as a boy's girlfriend and the future mother-in-law does not give a meeting gift, it may be because the boy does not have this custom locally. Afterwards, you can communicate with your boyfriend to eliminate any misunderstandings.
2. I may not be very satisfied with you
If there is a local custom of giving a gift when your boyfriend meets, and you brought a gift when you first met, but your boyfriend's mother did not prepare a red envelope, gift, or gift, it may be because your boyfriend's mother is not very satisfied with you.
3. The future mother-in-law is not clear about your identity
Another reason is that your boyfriend did not reveal your identity before visiting your future mother-in-law's house. Your boyfriend and his mother didn't seriously say that he was bringing his girlfriend to the house. His mother only regarded you as friends and didn't prepare a gift for you.
