My elder brother's daughter, who is now three years old, is still very quiet around me. A few months ago, I befriended her by playing with her, and she even pinky promised me that we are friends now and that we would talk and play together every time we meet. But when I met her again a week or two later, she was back to her old shy behavior.😅 And this showed me that if you don't see your children for a few days, they forget their promises. So make sure you keep seeing your niece, or this celebration won't last long.😄 Btw, she looks cute and happy to be with you! :)
