I'm exhausted, my daughter is knocked out, but can't go to bed because my fiance and his friends are recording in there... I've done more today than some do in a week, and I'm fighting to stay awake, so I went in to change into my pj's, and one is using my expensive phone charger that I can't afford to replace right now, and with their shoes on my bed, specifically my side, but apparently I'm a bad guy for being upset by this. No one asked if they could use my pillows or put their filthy shoes on my bed or use my expensive, sensitive phone charger, but I'm the bad guy for being upset...
