If you want to solve it temporarily, just say that a very good friend had an accident in a hurry, and I gave him the money, and I will pay it back when things slow down! Wait until the daughter-in-law is happy and find time to apologize to her! That depends on your relationship. Tell the truth if you have a good temper, and don't be angry with her for the time being if you have a bad temper. I have to explain the money to her sooner or later, so the lie can't be too true! White lies are expected to be adopted.
