Unaware/Meta-tropes

Justified

 * The relative size is so large that the relative non-giant being has a hard time getting the attention of the relative giantess.

Inverted

 * The giantess knows that the presence of small beings, but small beings cannot notice the presence of the giantess.
 * Although this situation sounds strange, it can be forced: the giant is invisible and intangible (like a ghost).
