i now have a new problem , my parents told me last night that i havent shown enough remorse, and asked me to write a letter of apology to my sister, i got a bit angry and refused and had a argument with my parents, now my parents have said that my disobidence is NOT acceptable and they are going to punish me again this coming weekend, they have said i will be locked back into my room all day saturday and sunday, more schoolwork and more punishment essays , this coming weekend is my cousins 16th birthday party me and my 2 other sisters are invited, i wont be able to go as i will be on punishment, my parents said i was warned well in advance if i didnt show remorse and write a letter of apology , i would be put back into lockdown and punished is this fair ?
