‘Me and You’ or ‘You and Me’?

A quick one for today. The other day I heard an Indonesian Chinese speaker refer to her (paternal) grandparents as “奶奶爷爷”. This immediately struck my ear as strange, as it’s usually said as “爷爷奶奶”. It then got me thinking about how it’s funny that languages tend to have fairly fixed order for what sounds most natural with ‘A and B’ sorts of noun-phrases.
