Were you sneaking? If so, and you have a high sneak skill and are equipped with muffled boots (or have the perk), and fortify sneak apparel, it might not sense your presence. (Skeletons don't have the sharpest of perception skills.)  We have had foes, even Deathlords walk right past us to attack followers on many occasions.

We have also met skeletons at an unmarked location near Broken Fang Cave that ignored us. (This only happened on one playthrough, but it was repeatable.)
