Llamas and the white lines on roads

Here is one that is a lighthearted observation,during this lockdown I have been taking Llamas for a walk around the neighbourhood and as there are next to no cars on the road I will walk them down the middle of the road.The roads have the white dividing line on them. I will walk down on that white line but do you think any of the llamas will walk on that white line,No,not one of them they will walk over it but not touch it.I take the Llamas individually and so far 5 out of the seven have all acted the same.
