4. Your Work Friends Are Your New Family

Remember when you spent hours telling your dear old mum how your day went? Well forget her, because apart from a stranger you see at Christmas and the occasional lump of money in your account, she's gone now. You will work, and socialise with your colleagues. Odds are, you may even live with one if you happen to enjoy coitus or halfing the price of your rent. They really become the only people you see. People you spent years and years with, side by side, you will only see them once a year now. Even then it's only a night at the pub around Christmas. That's why employers care so much that you're a good fit for the team, because when you spend 40-50 hours a week with someone you have to really like them. Like, a lot.
