My best friend told me that she was adopted by her father. She has no mother. Hearing this, I cried. How can I put it?

This bosom friend, you are very emotional and moved by your girlfriend's story. You are a good man, it's really hard to get! As the saying goes, "it is better to die than to die." My best friend's adoptive father raised her, and it's hard to imagine that her kindness is as heavy as a mountain. You should sympathize with, care for and take good care of your best friend, relieve her inferiority complex, and make yourself and her close sisters. The old man suggested that if your best friend agrees, your mother can recognize her as a goddaughter, and your relationship will be further improved. what do you think?
