What is 20 years old, sleeps all day, never lifts a finger to help around the house and thinks he was put on this earth to debate anything that comes out of my mouth? My nephew.. he's 20 today! Happy Birthday to the laziest, most arrogant, ungrateful, immature kid on the planet.. Why does he think he knows so much when he can't even pay his bills, or his rent, and is living in my basement working 15 hours a week?? I'm starting to think letting him move back in a month ago wasn't such a good idea.. ya think???
