Who could say such a thing about his/her mother....?

Today my classmate came to my house and the whole time she was complaining to me about her mother and that she took her phone away from her and stuff she said "I wish she would just die " when she said that sentence I got so mad to the point when I wanted to slap her like literally but all of sudden my anger became into tears I couldn't handle the pain inside me I don't have parents I miss them they died when I was little and because of that I had to live separated from my older sisters and because of it I went through so much and here is my classmate wishing her mother to die just because she took her phone away from her?.....I started to cry I couldn't handle myself then when I noticed that I am crying I smiled and wiped the tears away my classmates always complain about their parents and stuff it's not a big deal but I dunno why this time it broke my heart and made me cry...well I dunno about you but I appreciate what I got and I'm thankful for the things that I have because I know that a lot of people don't have a lot of the things that I have so be thankful for everything you have because you know life can take away everything you have in a second ❤🤗
