My friend's daughter got married, thought I was not here, and didn't tell me that I would give her some money.

If you want to give your friend's daughter some money to get married, you can consider getting in touch with your friends by phone, SMS, WeChat, etc. To express your wishes for his daughter's marriage and that you want to send some money as a blessing. In this process, you can ask their mailing address or bank account number and other information, and then directly call them the money.

If you want to send something in kind as a wedding gift, you can also contact your friends and ask them to provide you with your daughter's mailing address, and then mail the gift to your daughter.

No matter which way you send a gift, you should choose the appropriate amount or gift according to your actual situation and respect the wishes of the other party. In the process of communication, we should pay attention to expressing our blessings and wishes to avoid bringing any unnecessary trouble or embarrassment to the other party.
