[tlhIngan Hol] Who does {-oy} show endearment to

Someone says: {vIghro' leghbe' vavoywI'} for "my daddy didn't see the cat". The one who says this sentence, expresses endearment toward her father. On the other hand, if someone says {vIghro' leghbe' vavoylI'}, then what is actually happening ? Does the one who says this sentence, describe the endearment that "the other person has toward her father" ? Or by using the word {vavoy}, does he express an endearment on his behalf toward her father ? qunnoq
