5) Street shopping is a big no no
And by street shopping we mean money pinching. Basically by the time you are 30, you are an important person in the office and you cannot go to the team party and pretend to have no money for drinks. Sometimes you will also have to *gasp* pay for the other 21-year-olds, because ADULT!
6) You can’t be clueless
You can be secretly clueless but you are supposed to have gained wisdom in the three decades, and occasionally pass it on to the less fortunate 18-year-olds.
