of quadruplets hugging went viral last year. If you notice in the beginning one of the babies in pink goes to hug one of her siblings dressed in white. The sibling in white denies the hug and goes on to another sibling. All the other babies hug each other except these two.

Why does the sibling in white continue to deny the one in pink with the droopy diaper?

I would like some attempts at seriousness here but I did ask in social, so have at it.
