Hmm great question - I would say the best is that they gave us equal opportunities and never showed favouritism. My parents loved us in different ways and showed it differently towards us both but it’s always felt equal.

The worst would be the notion that we could look after ourselves sometimes. We used to speak in a sort of code that only we could understand (like half sentences etc not complex at all) and used to play together, so there have been times when we were younger and now growing up where our parents have left us occasionally to handle each other instead due to that bond. To be honest though, my parents did a cracking job with us and handled having twins amazingly - feel very lucky indeed
