I dont understand why every single time my boyfriend "helps" clean our room he just shoves everything in the hallway. Then while hes at work his mom bitches at me about it when i cant even lift half the shit. Like no one asked you to take forever and a day to move out because your to cheap to rent a uhaul and just expect everyone to jump and help you.
