After paying my family's water bill of $168 I am broke. I wish they would pitch In. Im the youngest in the house and pay it. My step brother has a better paying job than me and he literally don't do shit but lay in his room go to work and use my stuff in the bathroom and I clean up after him. It's not fair I get paid the least I am the youngest and I am pregnant paying for stuff they could do... that was my whole check plus some savings for gods sake I'm tired of this shit. 2 adults and 3 people over the age of 18 live here!
