Parents just don't understand.

So, when you ask someone a question the point is that youre seeking an answer..an honest answer. Not a.. maybe or a idk, no you want a YES or NO. Well one of my pet peeves is when someone tells you yes, you get your hopes up...then they turn on their word and tell you no. Ha, well my mom is famous for that.
I had to move from my home town, switch schools, and she told me that i could still hang out with my friends..LIE. She wont even take me up there anymore, and its her fault that i had to leave. I mean she doesn't even consider my feelings in the case that i love my friends and i had to sacrifice because of her, seriously. Today she told me she was taking me up there because i took my 2 exams out of 4 today and had a half day. Then she flips the script and says no you need to study for your exams tomorrow, um HELLO I'm an honoroll student! I think i know how to study and pass an exam whether i hang out or not, but evidently good grades isn't enough for some people.
Next time someone asks me a question I'm going to think about the 30th time my mom has changed her mind after telling me yes, and i will answer them SINCERELY, because i would hate for them to get their hopes up and for me to just crush them.
