"I'm getting married mama." As she points to my profile picture. In the picture is DH and me smiling down on baby girl as she 'signs' her adoption decree. I explain to her that no she is getting adopted. I asked her if she knew what the word adoption meant. She said no. I explained to her that on her adoption day we all agreed to live each other for always and that made us a family. She paused, pointed at the picture and said "I'm getting married."
The funny thing I get where she is coming from. Earlier in the summer she went to her first wedding and I explained it by telling her that when two people love each other very much they stand in front of everyone and tell each other that they will love each other for always. Just like adoption marriage is a legal commitment made to all parties to love each other for always.
The big difference is - someday kid you are moving out.
