My job can't expect me to wake up Tuesday & Thursday at 5:30am, do physical training until 7, go to work ASAP, work until 3, come home & take care of 2 kids, clean & do school work and than do all of that on Monday and Wednesday too but at work by 6:30am, work until 3pm and than do physical training from 5pm-6pm.... My body and my mental stability really can't handle all of this but when I say something about it all I get is "ah oh well" ok well how about all of you come do it with me since I'm so "fat" 90% of y'all are bigger than me so 🤷
