Two-faced dad

My birthday wasn't too long ago. Of course my family was actually decent to me for once. Til my birthday past and everyone was back to normal. For starters, it was Sunday breakfast. I have already gotten up to whatever i wanted and the one time i ask my mom to get me something, my dad snaps at me saying "don't treat your mom like she's your maid!" Bullshit! They make me do everything for them all the time and i complain in silence. Ooohhhh, but no when i ask something for the first time they get all bent out of shape! Geez, what the hell?
