Yeah, i'm yet to find a normal person who doesn't feel a pinch of pain at the thought or mention of monday, the only people who like them are those eternal optomists, and lets get real we hate them too. Maybe it's because monday is the furthest day from the weekend, or maybe you never want the weekend to end, and monday is always a rude slap in the face..
Research has shown that weekend lie ins on saturday and sunday, throw off your body clock, making you more likely to wake up late on monday, putting you in a shitty mood. This so called 'sleep debt' which you rack up during the week and use the weekends to catch up on increases fatigue throughout monday and tuesday
