Surprising

A few days ago, my senior in workplace retired. She is very kind, and very powerful. Although a farewell party was held, I couldn't participate in it. She sent a message for those who couldn't attend it like me on LINE. She wrote she was a housewife. I was surprised because I thought she was youthful. Then I said to the other senior that I was surprised at that. She told me she was 30's and she had a 5-year-old child. It was difficult for me to understand that! I thought I also wanted to be youthful forever like her.
