We're all monkeys

How much have you evolved since you were 15 years old? What are the things that you still do ever since you were that age? What kind of behaviors do you still hold to this day that you deem as completely normal, even though some people have always complained about it?

All of us have rules imprinted in our mind that we've picked up from our parents, then from teenagers, and finally from having to work and pay our bills. Most of them don't work all the time, or only work because we're acquainted with very like-minded people.

Certainly, some attitudes you have cause problems in romantic relationships, friendships and even generate stress between you and your colleagues at work. Yet, despite every complaint you've received, it's still there, because 'you're not going to change'.
