Those look like good dancing shoes. Will you be going dancing for your birthday? Age is just a number and its really noone’s business anyhow, so tell them whatever age you wish.
I went to a woman’s 102 bday recently. She walked into the restaurant by herself, smiling. Also, a woman I know who was 90 was just asked to retire. She didn’t fully want to, but everyone agrees she should have some time to enjoy her family and pets and relax a bit. Then, on the flip side, I’ve known some quite lazy teens and 20yr olds who are practically worthless, who would be out of breath walking a mile. It’s all in how you take care of yourself, how you feel and act, the number matters not. (except in court but I doubt you are planning any criminal activities. hehe)
