Well, most kids hate Sundays and I hate Sundays too. Its just that feeling that its the end of the weekend and you have to go back to stupid school the next day. Its really saddening... People rush to complete their homework, and text about 20 people asking for help or to ask what on earth the homework was. Then, they rush to do everything else and curse Sundays by saying "I hate you Sunday!" (That is the more elaborate way of saying what lots of people say - and I can guess you've figured out what they actually say)
