I understand her so well. Every single time when my parents throws or donate or misplace things I feel just like that. One time my mom was giving away my precious highschool uniform, the only reason I went to that good for nothing school was for the uniform, thank god she came to show off how good it looked on the kid. I felt bad for the kid but I shouted until it was given back to me. Similar, she again gave my childhood clothes to other kid, as it's not so important I let it go but wouldn't hurt so much for parents to ask before play with their kid's belongings.
