My mom worries about me every second

I don't understand my mother. Not one bit. Don't get me wrong I love her to death but I don't understand her way of thinking. Maybe it's just one of things that I won't understand until I have kids of my own. I can't believe she always worries about me and tries to talk to me on the phone every second. I don't really want to tell her that I am safe in the school even I can't go to city easily. I think until I were 50, my mom still thinks that I am always a child. Again, I don't have child now, so I will never think of that way. However, I love my mom and also my dad(Sorry to put you behind mom) haha~~Anyway I will take care of myself and study hard^^
