When I learn to crochet?

I've learned crochet from my mum when I was about 11 years old. My first project was a purse which currently I use to keep my needlework items. The pattern was from a Japanese book which was bought by my father for my mum as a present. The book is still in good condition and my mother really treasure it. The finishing of the purse was done by my mum. This purse was sewn with lining and a zipper.
