Going to work or school on your birthday is negotiable.
Never ever ever ever share needles if you absolutely positively must inject substances into your body. Better yet, ask us before you want to put that shit into your body. We spent 9 months making the best body we could for you and we will have firm opinions on what you should be doing with that body.
Walk around the house naked, just close your curtains before you do.
If, in an exam setting, you are asked to do something or answer a question and you don’t know, trust us when we say you will earn more brownie points by saying “I haven’t done that but this is how I would approach it” or “I don’t know but this is how I would find out”. (This is little hint as to how to get more marks on vivas or oral presentations).
Don’t judge someone by the music they enjoy, unless they enjoy Bolivian flute music at 1 am on volume 11. Then go for it, judge away.
Everyone judges everyone else. Know that, accept that because sometimes the judgements are good. Give yourself some credit. Mostly others will think you are ok or even better.
Know that people are talking about you way less than you think they are.
Never drink and dial ANYONE. No good will come from this.
