I'm not going to tell you that you shouldn't feel upset/sad. I love my bags, too. But knowing that a bag of yours made your mother happy should cheer you up; you mentioned that she's been asking for a while. It is just a bag in the end...your mother's happiness is much more rewarding, IMO!
I agree! You can always get a new bag later! lol! I love my mom so much, I buy her everything she wants!
