OCD or normal pre-school behavior?

Jai told me that Julia puts the crayons back in the box in a particular way. From what we can tell, right now it only seems as if she lines the crayons with the brand name facing up, nothing more, like we haven't noticed that they have to be in a certain color order. It's really funny as she says "no" if one of us does it differently & she'll change it.

She does something else that seems very particular, but I cannot remember what it is. I'll add it if I remember. Some behaviors are like any of ours, learned habits, normal, yet I wonder if some of it is due to my OCD tendencies. She observes & repeats EVERYTHING, you know!

Fascinating stuff!
