Prediction Riddle, answer this riddle!?

[Tony]

Noticed something bloom, then a key change, then a window close. Tell me what you think it means and why... answer gets 5 stars!

Life: One is born and a life into being (like a bloom on a flower), puberty is when the key of your life changes, you begin thinking about different things and begin acting differently, and the closing window symbolizes death - the ending of life
[makes sense in my head anyway!]

aging? Flower of youth, voice changes key at puberty, you close the windows when you're old and you can necver get warm
