Parents of teenagers will be familiar with the turn in their child’s personality: from playful, precious little pets they turn into blasé know-it-alls who can barely be bothered to raise an eyebrow to your fussing. 

Well, you little smart-asses, there’s a lot you don’t yet know. 

How to be an adult

You cannot call yourself an adult until you are able to do these things. I’m aware that many 40-year-olds would not fit this bill. Nor did I, long after my teenage years. But these are the rules. Fail this test, and you are not yet an adult in this here modern world. To be an adult you must:

1. Be able to open a bank account, deposit and withdraw money.
2. Have a credit record enough to get a credit card.
3. Personal grooming: learn how to shower, use deodorant, floss and brush, regularly without anyone nagging you.
4. Learn to drive and have a license.
5. Learn to break out of a procrastination cycle. Make todo lists for yourself on something more substantial than sticky notes and check them off.
6. Exercise regularly. Get outdoors.
7. Be able to provide meals for yourself: this includes grocery shopping, refrigerating when needed, operating the cooking range and microwave, and cooking basics like pasta, rice, eggs, oats, etc. Have a passing familiarity with spices.
8. Make grocery lists so you’re not going to the store for each item.
9. Maintain a set of email addresses and stay on top of spam.
10. Keep passwords secure, don’t use the same one everywhere, and come up with a way to manage them. Don’t use “password”, “123456”, or your birthday.
11. Don’t post embarrassing pictures or opinions on social media.
